3XV Crank rebuild
« on: August 24, 2018, 03:24:30 AM »
Hi everyone, just bought a 92 3xv4 off ebay today from extreme trading after selling my first one I brought in from Japan myself a few years back. Its a lovely looking bike in great nick, its running but needs the bottom end doing, they dropped 1200 on the price instantly so I had to have it, ive paid a deposit and im going to collect it today. Any recommendations on who to give the crank to and where to get the rod kits and mains seals etc. I know its been mentioned before but all the posts are pretty old. Any recommendations gratefully accepted, im looking forward to getting it on the road asap.

Hi

Yes that is an option probably the better one. You will get the rods big ends outer bearings and seals center bearing I am not sure center seal you can get one from me, or maybe someone on the forum is willing to part with one of theirs. That will be the longer option and slightly cheaper option but only slightly cheaper ;D

Lovely bike .
The best colours  (-P).
Chris Applebee in the UK rebuilt a sp crank for me  while back cost aproxx £400.
Im not sure what had to be replaced as it was in pretty good nick beforehand.
If you can get a new crank it's probably a better option.

I agree with Phil, Edd and Vinny. Chris Appleby rebuilt my "R" crank and can be trusted to source or the bearings/rods etc however the cost with labour and taxes is about the same as a new "R" crank (£500). The new cranks might be NLA (R and SPR) but give Andy at Webbs of Lincoln a call to discuss ( (01522) 513193 or 528951).

Webbs can supply rods and bearings. Grampian in bootle can rebuild your crank, they R cranks for me and Paul, but it's still the original pins and crank webs. Plus it's still an R crank. Last I heard SP cranks were still available new from Webbs of Lincoln

..... Its a lovely looking bike in great nick, its running but needs the bottom end doing, they dropped 1200 on the price instantly......
I spoke to Ciaran at Extreeme trading a couple of weeks ago and he was offering a warranty for the full price on his 2T's, however he was willing to reduce the price for a bought as seen sale. If you are handy with the spanners that makes his bikes a good price. And TBH most fresh imports need inspecting anyway so it's a win win, you get a cheaper bike and spend the savings on refreshing the engine and they sell a bike with no comeback

Just got back from picking it up, never seen so many bikes and cars all in one place, dude had 7 0w01,s 10 500lc,s and god knows howmany rgv nsr tzr, he had 7 nr,s ferrari,s porsches all from Japan. Im not planing on porting or different ignition etc, I  just want to rebuild the stock engine with the r crank and just try and get it as sweet as i can. Has jackel Japanese pipes, are they any good ? Sounds like i will need an nla seal, please pm me a price for it. So basically i can get a new crank with bearings and seals for around the same as getting the original rebuilt yes ?

My thoughts exactly, the prices in Japan are high now and the bikes are getting thin on the ground. Cheapest one i could find was 3500 quid some are cracking a million yen now ad in shipping and tax and its getting up there, so i ended up looking for nice stock bodywork engines can be fixed but they only look original once. So now my logic was saying 4 grand was good these days for this one with great bodywork

Chris won't know the state of the crank until he splits it. I sent him two and paid for both to be split. One was rebuildable, one was totally scrap. If the webs are shot you will need a new crank.

I'm tempted to sell my boxed/greased Chris Appleby rebuilt crank now and pay the difference for the SP one that Webbs have.... ;)

How much you want for it ? Dont think it was in stock back order from Japan. Whats the sp crank assembly part number ? I dont think it to bad it runs ok but you can just hear it.
