Not really, the 630 is rather tame for it's displacement. It could use a higher compression piston and some hotter cams and it would hold up fine as long as it's treated right, there has just been no significant aftermarket for it in that respect.
The bore is only 2mm bigger on the 630. Compression difference, 610-11.0:1, 630-12.4:1. How much bigger would be possible? and how much higher compression? Would 510 cams not fit in a 630?
All parts on order through Halls. Great customer service with these guys. I talked to Bob, he was very professional, keyed up all the part #'s & informed me right away that 5 parts were on back order. Was upfront that they'd possibly be in approximately one month maybe more. Everything has been boxed up and bike is already off the lift, I need it because I'm 90% to getting my project bike running. Looks like I'll be riding the WR & Ducati this summer, maybe I'll get lucky & the husky will be OTR early fall. I really wish there was as an Athena kit for it, it would be awesome since I already have it apart.
Eh, that was much easier than I thought. Lump is all buttoned up. Just need to put the airbox/bodywork back on, fill the fluids, give her a good wash & it'll be ready to go.
Sold it.......guy is picking it up on Monday. I sold my WR 400 too.....got a KTM SuperDuke R for the time being.......are the 701's coming stateside? And who's got em? I have to say this though........steer far from Roost Powersports in Thomaston, CT. Everything that could have been set/adjusted/shimmed/etc was wrong on that bike. The manual is very specific about the shimming of the cogs in the gearset, it was way off, both the intake and the exhaust cams were off by a tooth, valves were fine but I'd checked them each oil change, I can't recall all the minor mistakes but as I was disassembling the motor I referenced all the pics in the manual and more often than not things weren't right. Bike runs like a top now (it pulls noticeably harder through the rev range, starts on the first revolution of the motor and is void of any hiccups, flat spots or stumbling) but my ass is already chapped by this experience. Too bad, it's such a great machine, I really enjoyed riding it. I just can't get past the lack of parts availability or dealer support......it's cost me less than $1k in service/parts in 5 years, but then again it's only got 36xx miles on it......
I read that you sold the bike, but for those who might have the same problem it is the bushing with part number:8A0031503 that is probably the cause of the teeth misalignement on the shifter problem..
