anybody used elderfields engine rebuilders ?
Permalink  
 


so ive taken my engine to them as a last resort .i had the bore opened to 2.00 mm and had the head matched to suit but it seized within 10 minutes. the guy at elderfields said the place i took it to probably did the bore to tight (sutton rebore) .so now ive opted to have the whole engine rebuilt by proffesionals as im not doing it again myself .this way if it goes wrong its down to them . i dont know if i should try to cliam money back from them or not?

 

cheers

2.00MM bore? How many times you blown the piston up? O_o

PMJE are the best for rebores, or so everyone says.

I got a welder to do mine. No problems currently.

What you getting a full rebuild? Perhaps your jets are wrong on the carb and its running lean / rich?

BTW, if you're getting a full rebuild, you thought about Norfe? A couple of users from here have sent him their engines.

yea thought about it but its cheaper here £70 full rebuild and i took it to them directly ,and ive blown it up many times 1st time when i bought the bike ran it empty of 2t,had it rebored by a guy off ebay it then later snapped a ring and melted it to the piston due to it hitting the exhaust port ,then i put another piston in and it did it again as didnt know what the original problem was ,found the problem had it rebored but i used an old clip to hold the gudgeeon in and that flew off and did so much damage it had to go from 1.00mm to 2.00 ,this time ive taken it to elderfields and he says that sutton rebore have done the bore to tight causing it to heat seize hes also told me to go premix as its not worth having the oil pump on he gets 2 of these engines a week usually because of this problem

premix is good way to go Its not uncommon like you say for the pumps to fail. I haven`t got a personally removed mine proberly due to the fact, I`ve never had a pump fail on any of my bikes that have the autolube pumps & I suppose the convienience not that its a big deal to add. But If any of my bikes did suffer this then I would most certainly get rid of the pump and go premix

Premix would be no good for me, I don't know about you Stillbroke. I'll use my bike to and from work 6 days a week when it's back on the road so premixing will be a time consuming nightmare. I'll just double check the pump I've got works :)

Yeah but not being funny its common sense when your auto lube fails. Two strokes smoke hard. So
One day if you start your bike up and theres no smoke theres obviously something amiss no?

had a few go on me and they go QUICK lol once that seal gives and lets air in,its gone... usually at 8-10k....

clear oil pipe to check for bubbles and rebuild the pump when you do the piston/rings every 10k and it should be sweet wink
