Turning Wrenches / Basic carb question
October 12, 2025, 11:39:51 AM
I came across a set of VM32's for pretty short money and was wondering if they'd be fine to run on an RD motor.
Right now they're on an old 2T snowmobile motor.
If they'll work, what do I do about the intake boot?

Turning Wrenches / Checking the crank?
September 07, 2025, 10:23:41 AM
I have an R5 motor torn down and want to measure it to see if it's in spec before doing anything else.
I have v blocks, dial indicators, feeler gauges etc but idk what am I looking for?

Turning Wrenches / Crank work?

What's required to disassemble an RD 350 crank?
I realize there are experts who provide this rebuilding service but I was curious if this was something I could do on my own.
Thanks

Turning Wrenches / Back after 10+years
August 31, 2025, 03:41:33 PM
So it's been awhile and I just picked up a project, I have a roller RD350 and then I picked up a motor that only has a good transmission. Then a buddy found an R5 that has good compression, but is missing the carbs. For $300 I couldn't say no.
Anyway my goal is to put this thing together and put it on the track so I can race lightweight, formula 4 or maybe it's 3. Anyway.
Someone check me here but I'm pretty sure I can direct swap the gears right into the R5 cases, along with the clutch and shifter. I can also directly bolt up a set of RD cylinders?
Are the cylinders available from that eBay seller any good? I understand I might as well buy three sets in hopes of getting a set with the same porting. On that note, do they come with the same porting that was on the original RD's?
Any advice is greatly appreciated. Thank you.
