Crank rebuild

Post by jaybe64 »

Hi can anyone tell me where in UK can I get my crank rebuilt with mains and oilseals . I saw a post somewhere with someone asking same question about getting 380 done and a link but I can't find it now.

For a GT550? Do you need conrods too? If so, new ones are no longer available and new old stock rods are rarer than rocking horse proctologists.

A KTM rod can be used instead, but they are a little longer than Suzuki rods which needs a workaround (double base gaskets). A former poster had a crank and engine rebuild on his GT550 at a very well known rebuilder (I won't name them here) using KTM rods, and the pistons were clipping the head, requiring much diagnosis and a second rebuild, it was a LOT of faff.

Possible people to call who do 2-stroke crank rebuilds to chat about the options (others may weigh in with their additions / comments / experiences) would be Grampian Motors, PJ Engineering, Chris Applebee, Pete O'Dell.

Several places, Grampian (very knowledgeable and professional) is up there, as is Chris Applebee (done 2 x 550 cranks and a 750 crank for me), but a new guy from the Kettle Klub (spit) has surfaced and done a 550 crank for me which looks good - he only charges for what is required, rather than 'everything' so is cheaper. His work looks excellent.
Think of how stupid the average person is, then realise that half of them are more stupid than that.

Hi Alan,
It's been a while but I've a need to have my 380 crank rebuilt and I can see from this earlier post of yours that you mention a new guy who did your 550 crank. Do you have any information on him as he may be closer to me ( High Peak Derbyshire ) than some of the other companies.
Regards,
Glyn.

The KKK chap did it via BluesmokeBaz on Kettle Clinic, so best to ask on there.

Cheers Alan, Was the chap any nearer to the High Peak area ( Buxton ) than Grampian or Sep Kegworth which are both within 60 miles. Being an engineer myself I like to discuss the rebuild face to face rather than over the phone and then there's the chance of the crank going missing if I post it.

I believe so. They make a lot of their own stuff, or have them made - like the big centre bearings on the t500 which are nla.
