Ive pulled this ec250 and the spacer is 34-40-58 long Spring is 460mm

Rode it Quick update Took bike out for its first ride since doing head/squish/jetting and liked it, and never stalled it once even in tight woods What a blast it is to ride on trails, bottom end grunt is supurb, clean and smooth right through to a decent midrange, topend needs sorting as it...

:D That is exactly how it feels, like an old school 500mxer I'm going to drop compression to 12:1 this weekend and jet it a touch richer on the needle as I think I may still be jetting this like a mxer, as I was always looking for that crisp clean snap, this needs that 'edge' removing. Jakobi...

Gearing is 13/50 After initial ride I was going to try 13/46 as it is far to aggressive for my liking I'll look into the cams but its more off throttle issue or at least nearly off throttle

Mmm That just could be the issue here I have actually got the 250 topend that came with the bike, so I could experiment at a later date Would like to try to get this 300 right or at least better before throwing the towel in Head volume was 29.25cc with head laying flat, but piston dome would...

My chamber My head now

Thanks FS, sadly I didnt measure anything apart from squish before I removed head, thanks for link and thats how Ive measured it, three times actually, 24.3, 25.2 and 25.00 so around 13:1 ??? To much still ??? No detonation at all and Ive jetted it correctly, I lost that lovely lowdown calm...

Hi guys Right Ive got the 300 running best it ever has, squish now at 1.5(from 3.25) took 3mm out of head roof giving 20ml/cc of trapped volume, bike has excellent power, bit to much if Im honest and it stalls to easily in tight stuff Ive read other posts but theres conflicting info, what...

Happy Days Well my new needles arrived and its stopped raining so Ive spent a few hours playing around with this GG, Very quickly I had this dialed in and have great response and power everywhere, and I can now feel the difference in the maps Ended up with 42pilot AS 2 out N3CG in 2nd 172 main...

Thanks Jim Ive been reading a lot and have these few on my list and I'll add your suggestion to CCK CEK N3EG N3CG NEDW I don't have a clue of these sizes etc, just what Ive read Chris

Good tips there, but Ive just purchased a new boot RRP ?26 here in the UK Nice and flexy Chris

Hi Guys Ive recently bought an 09 EC which is/was a 250 and that's what it was advertised as, I removed head to adjust squish and found it to be a 300, the seller didn't even know ? So, Ive done squish and now need to sort the carburation out, I'm used to the older N style needles and have a...

300 Today I took cylinder of to adjust my squish, and found this has a 300 topend fitted, I thought it needed a smaller rear sprocket to tame it So, Ive set cylinder down and machined head taking the huge squish of 3.25 down to 1.55mm. Removed some from chamber to and had a psi of 200 so more...

Yes, I can do that too.It makes it easy to tweak the jetting for sure Chris

Rode it Well I had chance to ride it today on a tight woody ptactice venue, it was wet and slippy to say the least. Bike was fairly good at the end as Id changed jetting each lap (25mins) Im very happy so far and next job is to sort the squish and a few little setup things, bars are far to low...
