Hey larry i just ordered that off amazon. Looks good.

I dont think im at the skill level to be prioritizing suspension; my goals are body positioning and throttle control through corners.

I may be in ny for work in nov. Ill shoot you a pm

Re: Race Bike Build - Oct 12th/13th due date

I'm not too concerned about moped suspension on a smooth track with sub 50mph speeds. My bike's rigid, front and rear. But whatever helps you, go for it.

You definitely don't want to be riding a spongy bike with a lot of brake dive in the front, tho...

Re: Race Bike Build - Oct 12th/13th due date

mocked up rearsets after draining and replacing the clutch.

It had a 3 shoe with blue springs. Running a v1 jammer now.

Anyone holding onto replacement shoes?

You should be, cornering and braking compress the suspension accelerating and coming out of cornering unloads the suspension. something has to give under that force and if it's not suspension it's the contact patch of the tire lol. The relative smoothness of the surface isn't really the issue.

Re: Race Bike Build - Oct 12th/13th due date

I may come to this any one have Morini parts? Or engine? M1?

I have raced here a dozen times or so and what I took away was great clutch work that hits early and great brakes and a early hitting pipe! For the turns and the corners the straight away is up hill so 50mph is about it for top speed. The variated boys and girls are slightly superior on this track so beware. It’s cold here also and humidity is a strange factor.

Hmm whats the jetting change this time of year?

Re: Race Bike Build - Oct 12th/13th due date

Converted the tomos ebr to puch races and used a few spacers. 21 ball bearings.

The footpegs are good but need a 3rd point of contact for sturdiness.

Tomorrow is tightening up the exhaust and test rides. I need to dial in the clutch.

Great !

Re: Race Bike Build - Oct 12th/13th due date

Cleaned up the wiring. Soldered all cable ends after shortening. Rearranged the box. Also sleeved all exposed wiring.

what are you using for coolant?

Any recommendations? I was discussing this at the shop. Im running distilled water right now, and my head temp is PEAKING at 286 Fahrenheit.

That led me down the performance oil rabbit-hole, plug heat, and coolant options.

My main lingering question is: whats optimum operating temp for the cylinder?

I do have an EGT that will be on the bike eventually for more tuning and experimenting..(edited)

Thanks! I cant thank the guys enough for helping me along the way.

Re: Race Bike Build - Oct 12th/13th due date

i like maxima products so i use the Cool-Aide, but just wanted to ensure that you weren't planning on running regular antifreeze on the track.

Yea I was just going to run a hotter plug and distilled water

Re: Race Bike Build - Oct 12th/13th due date

You can try water wetter

Re: Race Bike Build - Oct 12th/13th due date

Series of ups and downs tonight. 5 more hours wrenching. Found a leak after blowing through the tank when welding a tab on. High risk and it smoked me.

New top speed though. Had some good hot laps tonight. Down gearing tomorrow and tuning clutch.

4. Install damper

5. Clean and oil chain

6. Install hotter plug

7. Run water wetter

8. Clean carb, upjet

9. Inspect clutch

10. Seat time

Good luck man...

Re: Race Bike Build - Oct 12th/13th due date

Good luck!

Re: Race Bike Build - Oct 12th/13th due date

Pics to be posted tomorrow! Got 2nd place in non-variated and 3rd in unlimited. What a great trip with a ton of help from rad people.

I cracked and bent my clutch bell, which threw the clutch plate retaining spring BEHIND the clutch.

Lucky for me a friend sacrificed/lent me their entire clutch setup so i could run my race.(edited)
