ESE's works engine tuner

[TZ350]

.

Trial fit of the chain on Chambers FZR/GP100 with a 13T front sprocket. At full extension the chain just touches the top of the swingarm and at full compresion its clear of the underside. With normal chain tension at the midpoint, the chain is not unduly slack at any other point in the swingarm travel. For Taupo and other long tracks Chambers plans on runing a larger front sprocket, 16-17T Looks like it should all work ok.

Chambers has also been busy fitting the rear wheel and front end from his old GP100 rolling chasis to his RG50. It looks the business with slicks on wide rims compaired to the original skinny RG50 wheels.

What stirling work...... I do look forward to team ESE winning a race...... it is long over due

This thread amongst other things is intended for those who are actually doing something, to post about what they are up too, and why.

And it doesn’t much matter if they are winning races or not.

For most, like me, doing well in our own way, is what keeps us interested.

Bucketiers who are doing something are much more interesting than the empty talk of the self proclaimed expert.

So Boys, its time you took your friend with the attatude, and all the silly talk some place else, may be over to his house.

Chambers is getting very close to being finished on his RG50, just a few things to finish like this bracket for the rear brake cable.

My own 50 is coming along, I have got all the cables, chain and ignition sorted now.

The side cover is cut away over the ignition stator so the timing can be easily adjusted on the dyno, the cover will be replaced when the engine is dialled in.

Next job is to cut the new squish and CC the head, aiming for 3cc or 8.5:1 corrected compression ratio.

Looking Good TZ, its good to see more 50s coming back out of the woodwork.

I think one of these will be my next project (only need to find a motor; as I still have a RG frame)...

and a new seat

17.7:1 that's pretty high. you may suppress high rpm power. Better to run lower & a smaller stinger/baffle angle.


Well I've been working on the 50 too. I've made up some ally bosses to be welded to the footpeg hanger mounts so I can lower the footpegs. It appears I'm getting older & its getting too uncomfortable for a long race. . . or even a short one.

Agree with Dave on this one, that compression is really really getting up there. If you get your ports and pipe working the trapped volume will be too great with that compression.

Thanks guys for the heads up, will revisit my calc and I can understand the need for improved riding comfort F5.
