Hustler class ( Vinduro Buckets)

its fixed Neil

I asked to get the new Hustler class thread tacked on to this one, hope so.

I guess Ill continue on with this thread now.

My choice, seeing as induction air pressure is not regulated. An XS250 engine, on its way to being reduced to a 150cc, 360 degree crank, twin. The gearbox and clutch are good for at least 40HP. A new short cylinder block is needed, pistons and rods are 2 x FZ250, engine block is that solid I think it will be good enough as a substantial part of the frame. The cam chain drive will be abandoned, the cam now being driven via the tooth belt supercharger drive that has to be there anyway. The points housing on the end of the camshaft wil now be a bearing support housing for the tooth belt drive. Extended camshaft with a taper and key to fit the alloy tooth belt drive pulley will extend through this bearing support housing.
Thats the plan at least at the moment.

okay I was thinking where the electric start was, or from behind the flywheel for the supercharger drive.

You guys still hard at it

What frame number are you up to now Scott?

[mr bucketracer]

Good question. 24 I think plus 2 unnumbered. Can't remember how to load pictures any more lol. ps Sorry to here about your dad )-:

A new camshaft and a new crankshaft. 4140, finish nitrided. A new cylinder block required, probably about an inch tall, the head will almost be straight onto the engine block.

TBH He wasn't so happy about it either, it was a year ago yesterday. we have only go as far as the yard on the tidy up.
Adding pictures is easy either hot link it with the insert image button or use the paper clip to access and attach it off the net address or direct from your computer.

Has your father started on the MC1.
Also did you bro finish the Air cooled RS.

[mr bucketracer]

The air cooled RS Is very yesterday lol even though a real good bike . He's on the first r15 Yamaha now . Iv just started building a 50 for myself. Iv built a cb350/4 race bike but some how smokes like a train ? Think the old time oil rings are crap

the r15

From memory the oil rings are 3 piece on OE pistons. If they're in good bores that shouldn't be the problem. Got stem seals fitted ? Head gasket isn't letting oil from the end galleries into the cylinders ? Not trying to get old rings rebedded on synthetic oil ? They had a few things wrong with them - but smoking generally wasn't one of them. The big-bore one I built bedded quickly on mineral oil and last i heard was still going well - but now in Oz I believe.

[mr bucketracer]

The standard pistons have a one piece oil ring . I rebored this . So new Bores ,pistons ,head seals , head gasket. I tried . Lucus mineral oil . Smokes on the 2 outer cylinders and one inner.

[mr bucketracer]

I then removed the head and cheaked I had put the rings up the right way . All good . I gave a quick rehone. Thought incase there something wrong with the head I set up another head . All in good condition. New seals and head gasket. Put the gray color castrol oil in .it seemed better but slowly getting worse on same cylinders. The head and barrels were surface ground. So flat as. Was told I should put thicker oil in it . Don't know what's out there. I was thinking take the plugs out and run it on the dyno with a motor driving it .

in the norty corner

First round done, stock standard AG100, no time to do anything to the engine. And its guttless, to top it off the gear selector started playing roulette, just when you needed the next gear down, too bad. Lots of stalling and falling. Have found the issue now and is fixed. Clutch got a workout.
So a bit more effort needed on the XS150SC twin I think.
Roughing out the crank today, 48mm bore x 41mm stroke, x2. Crank is 4140.
