Bucket update

[Skunk]

I've got one. don't know if it'll go small enough but we can try. If not a large hose clip - but that's not reccommended (right AJ?).

[ajturbo]

ummm not sure what your talking about there skunk...

[Sully60]

Thanks Sully, I've got the rings in their grooves now but might need a ring squeezy thing to get it to fit the bore. Anyone know if such a contraption exists?

I probably should have taken note of the way that they old piston was facing too. I'm assuming that the hole in the side of the piston is meant to line up with the inlet ports and not the exhaust port.

Most liners are tapered at the bottom and you won't really need a ring compressor if you're careful. You'd be right about about the piston, it should have an arrow on the top, this points to the front side of the engine towards the exhaust.

[Sketchy_Racer]

You shouldn't need a ring compressor on that. I've got a GP100 and had the motor apart and put the piston back in all good.

You mightwant to look at doing a couple of little things before you put it in.

1st: Set your Ring clearance. I don't know any numbers off the top of my head, but im sure F5Dave might be able to help you. Basically while you have the barrel off, take the rings off the piston, and put them in the bore. use the piston to slide them down a a bit and square them up in the barrel. Get some slip gauges and see what the fit is.

2nd: Where it rings locate on the pins in the ring groove, you wanna put a little chamfer around there with a oil stone.

3: Possibly good idea to dress the edges of the ring groove with a oil stone to prevent the rings from sticking.

4: Probably not worth the effort.. but maybe set the squish.. i think running around a 0.65 gap should be ok.

Anywho, Good luck!!

I think either was you put this thing together, she'll go mint

[Slingshot]

Father in law is coming over on Tuesday night and we're going to have a crack at getting this motor back together. Thanks all for the advice.

Frank is starting to come together now too, only major piece of work now is making the new rearsets fit and fashion a linkage for the gear shift. I've got the swing arm and the back wheel on, got the front wheel back on and have bleed the brakes.

Fark I love having an excuse to spend time in the garage!!

[Slingshot]

Have now got the motor back together and mounted in the frame.

Am having problems getting it to fire and keep running, me thinks there's an issue with the carb.

Sprayed a little CRC in and kicked it into life and it would run with a fairly wide open throttle but it won't idle and won't start without the help of the CRC.

Any ideas people?

[ajturbo]

it's fucked.. give it to me....


on that note... i got the GT engin back on the weekend....

not sure if i'll have it ready for the weekend...

needs
a rear tyre
engine put back in...

[Slingshot]

it's fucked.. give it to me....

Well maybe not....just managed to get it to fire and run briefly. I put my hand over the carb while I kicked the motor over after a couple of kicks it fired...stopped again when I took my hand off it though.

Are you racing at the slipway this weekend?

[Nasty]

Sprints clash .. its on Sunday

[Slingshot]

Got Frankenstein running!!!

Held my hand over the carb again and after a couple of kicks it just kept running.
Got the rear sets mounted, gear & brake linkages lined up...was almost too easy.

Just got to make sure everything is tight now and fit the fairings and I'm away!

See you on Sunday.

[Slingshot]

Right...I think I'm now all set to go for tomorrow out at the slipway.

Had a wee issue on a test run down the street this afternoon, the motor cut out and I ended up having to push the bike home.

Turned out there was a tiny piece of metal stuck between the electrode and the tip of the sparkplug. Ran fine again after I cleaned it and put the plug back in. I'm hoping that it was piece of shit from the old piston and not the new one.

Anyway, assuming that it's not pissing down tomorrow we should be in for a good day.

See you then.

Damp and windy conditions geeted competitors at todays bucket meeting for Round 4 of the SCS Promotions Champions held at the Slipway Driving Facility. With a depleted field missing regulars F5Dave, Skunk and Sketchy Racer representing the Wellington contingent for the Battle of the Buckets TT also being held today at Ruapuna.

With the weather looking increasingly bad the points races were held fairly quickly. The first race was held in what were to be the dryest conditions of the day although there were spots on the visor and the pace was not the usual of a completely dry slipway. The addition of much tighter chicane section also slowed the track down considerably whilst making for a challenging change of direction. Bayden made the best start and lead for for the early part of the race untroubled. I was in third from the start and after passing ? to be second I put my head down and tried to catch Bayden. I started to open the bike up properly and letting it rev ( I had been taking it a little easy as I was running in the new big bore pistons and rings) The improvement was immense and the engine revs hard all the way to 12500 and maybe a couple more quite safely. The mad ET 190 Vespa of Richard was now in third and and it felt like he was making ground.

Bayden by this time was running into traffic and I manged to catch up to him. I tried my first block pass at the bottom hairpin and despite nearly falling over from just about stopping at the apex I manged to pull it off I got to nthe top corner ahead of bayden but came up on Bungbung who I thought opened the door but then promptly closed it. I lost time trying to avoid him without going over the bars and Bayden managed to pull alongside and then past. As I was still close to him at the bottom corner I tried another block pass, this one was even sketchier than the last as we were coming up fast on Slingshot. I managed to get really tight and Bayden was forced wider onto the same line as Slingshot who at that moment ran out of fuel and stalled throwing Bayden off into the tyres.

I only figured this out after yet another heart stopping moment with a backmarker at the top corner where I didn't get passed and saw bayden stationary at the exit of the bottom corner, soon I also figured out the Richard had binned the Vespa and that Saxet was a fair way behind. I cruised the last two laps and took the win, a good result but I really didn't want Bayden and Richard to crash as they were ahead of Saxet who is close behind me in the points, still a win is a win and I did extend my lead.

As the fun races of the day continued my bike was getting very rattly at the top end. I kept checking this and apart from tightening the valve adjusters I couldn't make it completely go away.

The second points race started in basically wewt conditions with the suface of the track showing no dry lines and constant spots on the visor. Again Bayden made the best start and despite elbow wrestling AJturbo at the start managed to make it around the first lap in third spot. The race basically stayed this way to the end Qualman1234 was in second slipping and sliding all over the place try to get past Bayden. Slingshot was fourth in front of Saxet and going well until a loose engine bolt meant a second DNF. I was happy to maintain third as the engine was even noisier than before I wasn't being left behind despit not using the top 3000rpm and even manged to close right up to Bayden and Qualman as they made a few errors and avoided Bungbung who had a little sit down at the bottom corner.

Things were looking good untill the clutch cable slipped out of the bottom bracket so I had no clutch. I managed to be rough and just change down without using the clutch. I manged to bring the bike home in third by this time the engine was really noisey so I shut it down and threw it straight on the ute. Happy with my results and happy not to kill my "new" engine.

Also managed to get some photos of Slingshot, Qualman1234 and AJTurbo. Pretty shitty though didn't want to get the camera wet!

[Slingshot]

I managed to get really tight and Bayden was forced wider onto the same line as Slingshot who at that moment ran out of fuel and stalled throwing Bayden off into the tyres.

I hadn't stalled at this point...the bike was coughing a bit and I couldn't power out of the corner, I did manage one more lap before the motor ran out of gas completely and I coasted back to the pits.

Bayden over heard me as we were setting up for that race, I had just checked the fuel level and I made a comment to AJ "I'm gonna assume that there's enough fuel for the next race". Bayden replied "famous last words".
He was right.

Fairly wet and horrible day but the conditions make you concentrate pretty hard, I was shagged by the time I got home. I'm a bit pissed that I had two DNFs, I could have been in the points today with the small field and the wet track...oh well, will spend the next four weeks lock-wiring every bolt and then I'll be set.

Sully...thanks for the pic, you even made it blurry to make it look as if I was going fast.
