betarich Posted December 22, 2013 Report Share Posted December 22, 2013 (edited) Hi everyone I'm beginning to wish I hadn't bought this montesa now, I've just rebuilt the carb after the animal that owned it previous had bodged just about everything, it now runs sweet but the engine sounds terrible, I've removed the flywheel cover and there is play in the main bearings. Can anyone give me any rough Gide line on what these engines cost to rebuild? I'm an engine reconditioned so the labour isn't an issue I've never bought 2 stroke engine parts before. And are the engine parts available, bearings gaskets piston kit etc Where's the best place to get the parts?

lineaway Posted December 22, 2013 Report Share Posted December 22, 2013 You need to pull the cylinder and see what shape it is in. At that point you can verify if the rod is good too. As far as parts go, you would have to state your location. Quote Link to comment Share on other sites More sharing options...
betarich Posted December 22, 2013 Author Report Share Posted December 22, 2013 ive pulled the cylinder off and the coating is flaking in places, ill add some pics. the piston is showing signs of seizure at some point, these have recently been rubbed up by the previous owner. i think the guy new what he was selling as the engine was full of dirty 4 stroke engine oil, to reduce the knocking.

betarich Posted December 22, 2013 Author Report Share Posted December 22, 2013 the description of the bike reads, the pictures are taken today 2 days after purchase. ive been stung. but i guess not everyone is genuine, if anyone does have any engine parts for sale please PM me. 2002 Montesa 315 R 250cc Trials Bike.

guys Posted December 22, 2013 Report Share Posted December 22, 2013 I would at least try to get (a part of) my money back. It doesn't hurt to try.. Or at least give him a very bad review on ebay This guy knew very well he was selling a bad bike Quote Link to comment Share on other sites More sharing options...
lineaway Posted December 22, 2013 Report Share Posted December 22, 2013 Wow, I hope you still have the rev3. That`s not going to be cheap! Quote Link to comment Share on other sites More sharing options...
betarich Posted December 22, 2013 Author Report Share Posted December 22, 2013 hes denying all knowledge and said it was a good bike when he sold it to me, but i agree he knows it was shot, you can see the piston has been tampered with and how else would a litre of 4stroke engine oil get into the crank case. this is a vid of the main bearings before i stripped the engine Quote Link to comment Share on other sites More sharing options...
canada280i Posted December 22, 2013 Report Share Posted December 22, 2013 At least a partial refund to offset the repairs needed would be the least I would expect. I would guess you paid at least a grand if it was up for $1200 so a couple hundred back would be the right thing to do 1 Quote Link to comment Share on other sites More sharing options...
betarich Posted December 22, 2013 Author Report Share Posted December 22, 2013 i totally agree, ive spoken to the gut via text i havnt complained about the other bodges on the bike or that the jets were loose in the carb, i basically want the full cost of parts or at least some contribution and ive said i will build the motor myself to save a little, but hes basically said no. im trying to reason with the guy but hes just not interested in the slightest.

tltel Posted December 22, 2013 Report Share Posted December 22, 2013 If you paid cash I don't think there is much you can do, but if you used Paypal you can reverse the payment as the bike was not as the description. TLTEL Quote Link to comment Share on other sites More sharing options...
maxbikes Posted December 23, 2013 Report Share Posted December 23, 2013 sorry but he has bodged this bike up to sell,your not going to get any money back.so bite the bullet and get on with it.we have all bought bikes we wish we had not.as its a private sale there is no come back.pity about piston,if it was only main bearings it would only cost £25 to repair.and few hours of labour.

joeninety Posted December 23, 2013 Report Share Posted December 23, 2013 Sometimes these things happen. I bought my Sherco off a mate and after a month a main bearing let go and part of the bearing cage got into the cylinder and scored the barrel similar to yours. He felt dreadful and gave me a small sum back but I wouldn't accept anymore as he sold it to me in good faith. Sometimes these things happen, but I suspect in your case the seller probably knew... Moving on, I see two options. You either break the bike and sell spares, I'd have thought you probably get 3/4 of you rmoney back at a guess but a pain in the back side or you repair it. If I was going to repair it I'd be asking the following question, whats the rest of the bike like? Things like head bearings, linkage bearings, brakes etc? The 315 is a good bike and I would possibly do the repair, its going to cost you the best part of £500 if you do it yourself but then you will know its all done and pukka whereas you could scrap it and buy another "cheapie" and end up with the same problem as, lets face it the bike is getting on a bit. Parts like gaskets, bearings, even pistons and fairly cheap but the main cost will be getting the barrel re-plated. It'll be Nicosil plate and the company in the UK who does that is Langcourts. When I had my Sherco barrel done I sent it off to Splat Shop and they were fantastic and sent barrel away to Langcourts for me and was then sent back with correct piston and all the parts I need to rebuild. I would give them a call to see if they could do this for your Montesa. With this service you will lose the barrel for about 3 weeks, this gave me plenty of time to total strip my bike, clean & grease everything etc. I think once you get it back together you'd have a solid bike for a good few years. The bottom line is you could buy a 08 , 09 , 10 year bike and have the same issue in a year or sooner... Hope this helps! 2 Quote Link to comment Share on other sites More sharing options...
