no doubt...i'll let you know too danny...

Danny I think tommorrow I should call that dude, tell him we don't care about the shitty sheetrock work in his garage, or that he doesn't like to wear a shirt, we want pics of the bike!

Is CDI units from 1989 to 2001 the same? Specifically I am wondering if the coil and CDI from a 1997 CR 500 engine will work on a 1990 CR 500 engine? Thanks ...

the electronics from '87+ all interchange

hey i cant get things together to get that vegas bike

Cool head cylinder heads claim lower engine temps but they look higher than stock heads. My question is has anyone tried to install a cool head into a Gen 1 conversion - given that engine head space is already in jeopardy. Will the cool head work at all in Gen 1 conversion without modifying the gas tank?

the only thing in jeopardy is your plug clearance with your cap on...depending on how much you tilt your engine a shorty plug will most likely fit...but you would have to take measurements before buying it for SURE!...cause i don't know how big these 'cool heads' are mind you...

unless you buy it to run an alky dome, a coolhead is a waste of money.

Thanks I will save my money for other project parts.

on a gen 1 you use the stock lower mounts so theres no tilting involved right?

Yes.

Will the coil from a 1987 CR500 work on a 1990 CR 500 engine? I bought a 1990 CR500 engine - just bored to 91 mm, ported, etc - let the project begin!

Sorry guys I realize this has been answered - been up for 21 hours when I wrote the question - should have went to bed instead. Sorry to waste your time.

I think I know the answer but I want to be sure - is the float height in a carb specific to the carb or the application? In oher words if I took a PWK 38 from a CR250 and put it on a CR 500 would I need to change the float height or just the jets? Logically I would think the float height is specific to the carb and I would just need to rejet.

just the jets, maybe the needle. 250s and 500s use a close tune, so you could try it as it, then just fine tune to get it perfect.

Yes it's specific to the carb

I have a 1990 CR 500 motor which I will use in a AF project. I asked before about the electronics and someone said the electronics from 1987 onwards are the same. Well I am looking at a CDI from a 1988. My question is will it work without modifications to the wiring or will I have to fabricate the connections? Is the coil the same as well - wiring and functionality?

let me ask you, why would I tell you all of the electronics from '87+ interchange if they didn't?
some of the timing curves in the cdis changed over the years, but they all interchange.

I want a CDI that will work with the 1990 (had a 1990 CDI) so that I do not have to fool around with the timing. What year range has the same timing curve as the 1990?

there were very slight variations, any year '87+ will work fine
