IM NO EXPERT. but i read once that ideal duration for exhaust is around 190 so you seem to be good there. people tell me that you want your transfers at about 130 degrees though.

Sorry man, im glad your ok. seeing that bike all bent up brings a tear to my eye.

hey burnt add me to the list im in!

Nice mr wheelman. its good to see your going to set up the port timing.

i would think It should at least run with those jets

I would like to add some thoughts. One thing that hasnt been mentioned is port timing. your port timing is alot different with that ministroke crank. That ruima bore on my stock crank doesnt clear the exhaust port and barley clears the transfers when all the way down to BDC. so when you shim the cyl...

sanjuro what you running for parts on the mhr?carb,pipe,ect.? man i would think that bike is going to crank with that MHR and the burial pipe!

Ya i hear ya. im happy with 55-60 mph. with good take off. im sure BTs corsa reved alot high than this cheap heavy ruima piston and poor casting.

for reference. 51mm ruima,stock crank, pg long, 9.2-1 gears(16 x 42 i think),stock tires, 28mm oko 150 main, 55 pilot, needle in the middle(i think,cant remember) I did 56.5mph for a base line the other day. without any trans/carb fine tuning im sure i can hit 60 with fine tuning. can cruise 45mph n...

thanks burnt! im in pending on price.

I was told once that the exhaust port should be the same size at both ends. (opening at piston and opening at exhaust)

Anyone know if thats true?

The 6 petal compared to 4 petal reeds will improve the bottom end and mid range throttle response and performance. The old multiple carb adage applies here, "a lot of little holes is better than a couple of big holes." The top end will not be hurt and depending on the area of the reed ope...

I want to get rid of it. Whats the easiest way to do this? Has anyone found one that will screw right on?

Greetings: Headbolts remained tight. Gave 'em an extra 1/6th turn anyway. Exhaust flange just a bit short of snug, with some smoke staining around the block; tightened them up a bit too. Now with needle 1 click rich of center felt a bit rich of ideal all over, with temps between 250 and 350 at all ...

im interested. few questions though

Whats the difference in performance between the 4pedal and the 6? Do we just get the reeds or do they come with the block also? How is the block different from what comes with the ct manifold? thanks
