Guys, really appreciate all the advice :-) newsh - this is not a run of the mill dynojet kit - it is the 'needle jets' themselves with installation tools. Enlarge the attached pic, I have yet to talk to anyone who has seen this kit before, don't even remember where I bought it, it was so long ago, l...

Hi Jompy, I did that when I installed the 2nd set of coils, no harm in doing it again. Cracked liners, aside from removing the head, is there any other way of checking? Only heard about this problem on R1's recently, I really hope it's not, any other symptoms? Already purchased a SRF098 fan switch t...

Very nice guys, mines a little rough round the edges, it was poorly stored from 2014 until a couple of months ago, life just got in the way. I'm enjoying the quiet standard can at the moment lol. I've been reading about these bikes suffering from cracked cylinders, has a potential cause been identif...

Mine started this morning with no choke....

I didn't buy mine until March 2000, a leftover 99 model.

It was most likely the same one, I didn't have anything to contribute so I didn't post much. probably read every post before I bought my R1

Hi Newsh, I have 15's in these carbs, the are from a 2000 bike I think. Ok, I thought I read the carbs were 3 1/8 turns out somewhere, my mistake, I'll try 2.5.
Do I recognize that name from the old original R1 forum about 20 years ago ?

Runs a little better with the standard can, but very rich, started with no choke and needs a little throttle when starting warm.
Maybe turn back the air screws a turn ??

Had a busy day, but did have time to look at the exup, it moves fine, and there is just enough slop in the cable for me to freely move it by hand slightly, so cover back on using the one bolt I managed to free. Double checked the air screws were 3 1/8 turns out. Put the standard can back on just for...

I did read a post regarding this, someone had wired 12v directly from the battery. The coil connector close to the TPS is nice and clean, I lubed with a little acf50 to keep corrosion away.

That would be a nice run to Dorset if the weather stayed as it is up here today

I have always seen the motor and cable move perfect fine, I just haven't actually watched the valve turn under the cover.

Thanks, I won't be able to look at the bike until the weekend, I'll be putting my carbs back on, and if I can find my CarbtuneTool, balancing the carbs, then snapping off the exup cover bolts, lol, to check 100% it's working.

It does it with any throttle input, how do I check the tensioner ?
Thanks

Hi Moise, the issue got progressively worse, same problem and instead of just feeling like a little 'miss' about 2000 rpm, it got more pronounced and lasts up to maybe 3500 or so. Obviously worse when under load using higher gears, no fun at all with a passenger in town.

Hi Moise, yes I have changed the plugs In the past and no change, bought another set of coils and plug caps as well. I'll try and balance my carbs and if no luck with the idle I'll put the original screws back in. I am fairly sure I will find the exup working. Bought a crank sensor years ago, but ne...

Will do, have the carbs off and hope to pick up some Allen bolts for the float bowls tomorrow, will be the weekend before I get to look at the exup.
I will report back what I find.
Cheers guys.

Thanks guys,I will give it another check, I did check it before and it was moving as expected a number of years back,was fine then with the same symptoms. Was going to do it again a few weeks ago but the cover bolts have siezed, I broke one off, and decided to leave the others alone as I'm 100% sure...

Hi guys, I have owned a 99 bike from new and its been off the road for the last 6 years, got another bike and sort of lost interest due to a running issue I couldn't resolve. This is not a problem caused by old fuel not being drained, in fact after buying a new battery it burst into life after about...
