Rangi da Munta.

[Kendog]

So you've changed your mind about 2 strokes? They ARE kewl eh!

This one certainly is.

But I still love the 4.

[nudemetalz]

Just has a little "traction issues" in the pit area, ay Trudes,.....

[Number One]

tee hee hee I got a run down of it when Sully got home

I got to ride Rangi for a few laps at the end of the racing today. What an awesome little bike, it's so easy to flick around and the engine is sooooo smooth.

Great work everyone involved in putting this bucket together, it rocks

I too had a go on Rangi, what a beast!. Good job too sketchy for doing such a awesome job on the engine , Silky smooth! and free reving.
Too bad it was slightly wet, so i didn't try too push it.

Why did you need to push it? Did it run out of petrol or something?

Took Rangi out to Kaitoke yesterday to have a wee play....
F5Dave mentioned to me about the possibility of changing his front sprocket (a 13) to an 11 so that I can get him into 6th gear at Kaitoke, so after talking to Boyles and finding I couldn't get an 11 front sprocket and some calculating of numbers we decided to get the same ratio I could put a 47 rear sprocket on instead.
So we did that over the weekend and after telling Skunk, Sketchy and Quallman what I'd done and some sharp intakes of breath and comments of "I was tapping it out in 6th at the Slipway before" and "That thing already wheelied in 1st and 2nd... are you sure you know what you're doin?" I figured I'd test it and see before I put the old sprocket back on and learned to ride faster.
Admittedly I didn't try any standing starts to see what kind of evil it would produce, but I'm now getting the full benefit of having 6 gears. However, I'm not entirely convinced and am thinking I should get a 43 rear sprocket and try that..... oh the possibilities....

[F5 Dave]

Will take you a little time to get used to more gears but you should have noticed that it was more spritely in between gears. No point having 6 if you only use 4.

I had said I'd get a 12, 13 & 14 & an 11 if you could get it. I've been searching for 11 & no dice. If it wheelies too much move the seat further or bars lower.

[Trudes]

Yeah the bars do need lowering, looking at putting some new forks on so we can do that, got a new bottom for him too, just need to fit it.... and I need to remind myself to lean forward upon launch!!!

[F5 Dave]

. . "I was tapping it out in 6th at the Slipway before" ...

Yeah right, I don't even do that on the fiddy

[Trudes]

That wasn't me.... that was Glen

[F5 Dave]

On the H I used to sit on the tank to race start, but it helped that it was fairly flat with the seat. Would still come up, sometimes into 3rd.

So how did it feel with lower gearing? Did you suss the new gear change spots & how was acceleration?

[nudemetalz]

I would have thought an 11 tooth sprocket would be quite hard on a chain (no, not hard-on !!), but I guess we're not talking 180hp.

[F5 Dave]

No drama on a 420 chain, bad on a 520. Bigger is better, but having a good range of gearing is a boon.

It felt like it was just constantly reving, first is a bit of a nightmare, thinking I might have to rev the snot out of it and dump the clutch in 2nd to get a start without it doing uncontrolable wheelies.... but will give that one a bit of practice I think. It didn't seem to do much in 2nd to 4th gears, just rev and it pulled quite well in 5th and 6th... Nigel said I was pulling away from him on the straights. There were a couple of different gear change spots, but basically instead of going around corners in 3rd I was usuing 4th and the clutch instead.... will take some getting used to, but it was good to get it into 6th! (Oh, and I've fixed my fuel line like you said too, but it seemed to flood itself a couple of times yesterday which was strange).

[F5 Dave]

Once you get going the higher gears will be closer together which is good & if it is dusting the 150 all the better.

Keeps constantly revving? erm sounds like clutch slip, maybe ask someone to ride it to see what they think. You should have noticed a real urgency increase.


With the fuel the level may be a bit high, or the sealing is a bit average & with the better fuel supply it is showing up. Those tanks rust pretty bad so they will have some junk in them. Clean the carb out & check for debris, if there is you may need to seal the tank or make a tank like Fishies 50.
