Will I get my 100 ready in time for Taupo?

[Buckets4Me]

I have been offered that before, but the thought of folding into a RS sickens me (It may as well be a mini bike as far as I am concerned)

Still I must have ago on one of those delta frames one day soon

wait till rick gets his a into g and coppies one of the gp engine and get 50% more boom for his buck(then there will be no way that the derbies will keep up unless they do something different)

and yea I'm sure that chambers will lend you his bike if it turns up at the track again
wonder when he is going to get his gt125 going ?

Oh yeah, I forgot to post:



EET LIEEVES!

The wife was out with the kids so I had a few min before setting off to racing to roll it down the drive & it started up. I poured some water in & it started leaking from the pump gasket, [hmm, thinks now maybe I didn't do that up fully when I worked out it went backwards]. Either way it did pump some water, just the wrong way around so I might seal the pump, reverse the hoses & try again.


Sadly for the 100; my 500 parts are here & that takes priority.

[F5 Dave]

Well now the Dirtbike is largely sorted out I have had a mo to look at the 100.
Impeller rubs heavily agaisnt the housing. Seems the welding has once more distorted something, thanks Melmac. Ground that out.

Still leaks after a new gasket. Some hoses have damage so cut down or replace. Last leak, on water pump outlet hose join. . . hmm, hold on! - its coming from the pipe. which was welded on. badly. Out with the JB epoxy to seal the join. This should cure it. Pipes swapped around so the water should pump in the correct direction.

The brakes need some attn, the bigger calliper really needs a bigger MC, so I try the 'Brenbo' one I have lying around, but it clouts the fairing stay due to small clipons. I'll try rebleeding the old MC & see if I can get it adequate. Need to make a footpeg. Then it's ready to try at Easter. Jet it & it should be good. Well, good but on skinny wheels with old old tyres. Oh that's right the clutch bracket needs some major redesign as it's on a bastard angle.

Easter! but thats waaay before Taupo!

[F5 Dave]

ooh Friday afternoon & its upgrade time as another bucket slides it's way into the F5Dave stable to shed a few parts, however it won't be the death of a bucket. There will be some swapsies & two bikes will emerge, just it makes the 100 more viable quicker & I'm time poor at the moment. Not that I'm cash rich, I've been haemorrhaging money on Dirtbikes & the 500.

100 holds water. Need to sort some more engine spacers that I had omitted in the haste to spark it up & prove water pumping concept (actually I need to run it now the pipes are reversed & see that it circulates with some speed, looked like it would). If the weather stays like this I might get to the dyno in the weekend (along with the 500).


Hmm I've just thought of some more bits I can sell to recoup a tickle.

is Taupo on again this year ???

You should have less projects you would get more done.... okey:

[F5 Dave]

Yeah thanks for that snippet of wisdom. Seemed far funnier/smarter when I am administering it.

Well instead of going racing in the rain I took the 500 & the 100 to the dyno. Another depressing day.

Well it starts & seems to circulate water. Wrong way again?! Well it sounds crisp & awesome. Hard to start as compression is too high with the gash head. well it starts easily enough, but needs a decent bump start.

Threw it on the dyno to see if it would spit its guts. Ran up real well through the gears on the first try. Getting cocky. Lets load it up. Bwoooooh. ok that's not too flash, lets pop it up a main. A bit better, ready for another size up. Bear in mind that this is the first time it's run in any sort of anger, just a carb bolted on with whatever an RGV VJ21 came with & the ignition where it stands.

Won't hold full throttle (hey I'm not into double hp figures yet, jetting is miles off). Hmm, water missing from clear hose pipe. Stop engine.


Refill. Takes a litre. still going down. Maybe it's not bleed, the pump needs a bleeder on it. Water still going down.

Ok game over, where is it going. Take off pipe (was leaking water jacket to ex port, thought I'd fixed that). No water in pipe.


hmm. Check gear box with torch. Hmm, that's pretty full of water right there. Seal must be totally open. Take it home & drain & flush with kero.

No way this is going to be finished by easter esp as I'm off on business for 2 days this week.

When is Taupo next on? I'd already spent a number of hours de-bodgeifying the new donor bike.

[F5 Dave]

Well the leak was easy enough to work out. The special spring loaded seal was there. But the main seal wasn't thanks Melmac where the hell did you put that? Obviously it got melted in the welding process & he neglected to tell me he'd hooked it out 15 year ago. OK so I bought a new seal & bearing that had seized, but stopped short of the spring seal which has a split in it. At this point I almost ordered an electric one, but I've run out of play money, so its on the cheap from now.

ok so I figured I should try the pump with the battery drill. works well one way, but doesn't work at all the other way.

You guessed it, the way that Martin convinced me it needed to spin. & here's me with no money to get around this issue. hmm. maybe I could thermosyphon it. Seems unlikely as the rad is largely below the engine rather than above it.

ok what it I take off the old gear & put on the original kick start gear? Well a session on the lathe doesn't remove enough of the weld. But the angle grinder makes it square & smaller. I cut down the shaft a bit & press on the kick start gear & place the idler gear on the gearbox shaft it lives on (amazing that I've kept these gears). Now I have a water pump that tuns the correct way. hozzah! Maybe Martins' last sabotage attempt is cured.

Found a 16mm plate that will make my new footrest hangers. Dropped them off to a mate with a bandsaw to rough them out then I'll spend some lovin time on the mill.

I've rerouted the clutch cable holder to make a straight pull & modified the cable.
Now all I need is to swap the swingarm over & fit the new hangers & brake controls etc + the front end.


Then maybe a trip to the dyno to see if I can break further into the double figures, -heck it may even be able to run for the 19th June Kaitoke meet.

Then I need to finish the new head as the present one is stupid (thanks Marty).

Then fire some decent jets & timing to it. Well then make one of the pipes I designed 13 years ago, or even just start the new barrel, as I'm not happy with some of the choices I made all that time ago.

[Henk]

Shit Dave, next to nothing left to do. Can I take it for a spin on the 19th?

[F5 Dave]

oh yeah, it'll be ready. . .

[F5 Dave]

Well a bit closer, the footrest hangers are roughed out & drilled. Just need to counterbore the footrest holes & drill & tap the grub screws to retain the peg pivots in place, then mill them pretty & lighter, but that might take a back seat to getting operational. In the weekend I plan to finish the hangers, swap the rear end s/w wheel & disc brake setup over. Then having finished the side cover gasket (special due to water pump being welded on) I started last night, just needs bolt holes punched, - pitch it together & fill with water & oil.

I may quickly pop the head off & Toroid the silly shape as the comm is silly high & shallow. Then its ready to trial again. Will finish the real head later. Maybe.

If it goes ok then just the front end to swap over if I feel like it, & nyloning for the track. Will be on older rubber but should be ok for some laps to see how it goes & stays together.

you must be a old man old now been around for ever lol what reat home you in

[F5 Dave]

Smart Prick. So when are you going to come down for a race? Or at least showcase some bikes?

Well I put the engine cover back in & trialled adding water. wp gasket leaked so some master gasket & I'll try again (the cover isn't entirely flat due to dodgy welding).

Swapped the rear SW etc over so now the rear wheel is the wider RS one. Of course nothing is easy & for some reason the original builder had done some fanukering to make it all fit for the new engine rather than the other way around (as my 50 is, which I thought was the logical way to do it, but perhaps took longer with the grinder). The sprocket is too far inboard.

So more time making up spacers. Also the rear wheel gets jammed in there so is hard to remove. Hardly ideal, but I can 100% solve this by fitting a wider bearing.

Had to take a 420 rear sprocket down to 415. Tricky job on the lathe, better to do it on the mill, but I have use of the mill at work, not at home. Set up the rear brake on the hanger & worked out where I can mill some ally off the hangers.

You know it's actually getting close. All I don't know is if the engine will hang together water & seal wise & if it will perform okish.

[crazy man]

l will get back out there one day just finshing of a project at the moment a f3 bike then the buckets are next! will hopefully turn some of my crap into something a bit nicer. just hope my body is up to it. will get some pic's of the bikes in the next week up here always good for a look!. pull out a old tape with you on the mb 100 at taupo
