Good Job Modified piston/liner and crankshaft reason price RB, NovaRossi,Picco and Rossi h34r: Look at web http://rbmods.net Good Luck!
i received my 2 nova rosi 35 plus 21,s today,, very impressed indeed.. i used to run macs and cmb 21, s but when i raced a few months back against mr ian , nitrocrazed with his nova . well , all as i can say is if he didnt fall over during the heat, i couldn,t catch him, and i had a andy brown moded mac running hot, so that why i changed,, the nova,s from rossi sales seem to be a one type of model and thats it,, i have never seen a frank orlic moded nova to date, but hear good reports about them,, pitty frank does not do the moding any more,,
im racing with arron from ozspec in january at the world challenge down here in sydney, australia,,
hopefully some of you americans come out with 21 riggers and even some frank orlic moded novas,,
arron, ian and i will be be glad to go head to head in the 21 rigger class , and see who,s hot and who,s not,, , just my 2 cents worth,,
nova 35 plus 21,, race one or chase one,,
Thanks for the great pix Ian!Some pics of the engine and components.

Looks like the water jacket was a bit of an afterthought, any problems overheating?
I've been running this style crank in my .21 WS-7's. you cut the shaft and recess the flywheel to accept the collet. I've had great success with the car engine in my boats.I'd like to see how you deal with that style of crankshaft when used in a boat. What do you use for a flywheel and a collet. Are there production pieces or homemade?mike b
A question I have about the motor is the silicone ramp in the crank.With running 60%-70% nitro in our boats, how long will the silicone last before it is digested in the motor.
It's really silicone not epoxy?

How many threads do you expose when you cut the flywheel, and what is a ws-7? even though it has the pilot, the crank is still threaded 1/4-28 right.I've been running this style crank in my .21 WS-7's. you cut the shaft and recess the flywheel to accept the collet.

No problems with overheating. Enduro racers (FSRV Naviga) race them (geared) in heats of 30min without problem..

The silicone starts off quite hard, but I had the issue that Petr mentions (I didnt know about the chemical attack problem! ) so I removed the silicone from my engine: https://www.intlwaters.com/gallery/displayimage...=241&pos=60A question I have about the motor is the silicone ramp in the crank.With running 60%-70% nitro in our boats, how long will the silicone last before it is digested in the motor.

Waltr,
This silicon ramp is very sensitive (gets damaged) to many cleaning oils like WD40. WD40 will blow it to a balloon and it will get loose. So far I know Corrosion X has not this adverse effect.
