Crazy88 Posted October 13, 2022 Posted October 13, 2022 Fuuuuuckkk.....the bike shop has told me my engine is fooked... Its a Mk1 1200 bandit The damn thing is smoking good and proper so ive decided that if it needs to be rebuilt I may as well go big bore and get it done and out the way. So Im after advice as to what to do and any recommendations on who could do the work? Was thinking just a Wisco 1216 kit and gas flowed head Is it worth doing anything to the gearbox? It will be stage 3 and dyno'd after. Any advice is welcomed/pros/cons And anyone with a mk1 1200 bandit engine already done for sale? ROFL!! Quote
wraith Posted October 13, 2022 Posted October 13, 2022 Depending on who Meany miles it has on it, look at the crank shells (big ends) cam chain, cam chain blades. Gear box, if you don't have a problem now leave it. If he hasn't retired yet Roger Upperton Leeds is one of the best I'd say. Quote
fatblokeonbandit Posted October 13, 2022 Posted October 13, 2022 Mileage?? did it just start smoking or getting worse over time?? is it running ok apart from the smoke?? Quote
Crazy88 Posted October 13, 2022 Author Posted October 13, 2022 (edited) The bike has been standing for a while 18 months or so, but when i was riding it, it always seemed a little smoky but i thought it was a mixture issue. So when i got round to getting it back road worthy i had the shop play around with the carbs as they seemed to think it was a fuel issue, they got it working but now it smokes heavily as the engine warms up also wont rev above 3k. So now its a toss up about what to do. Milage is about 22k and yes it was running ok prior to these issues. Edited October 13, 2022 by Crazy88 Quote
fatblokeonbandit Posted October 13, 2022 Posted October 13, 2022 It’s carbs, get them out and clean them correctly, 2 Quote
Crazy88 Posted October 13, 2022 Author Posted October 13, 2022 (edited) Thanks buddy Whats the best way to clean the carbs properly, I would have thought the shop would have done it....mmmmm How would the issue cause such heavy smoking? Im based in Surrey? Thanks again Edited October 13, 2022 by Crazy88 Quote
fatblokeonbandit Posted October 13, 2022 Posted October 13, 2022 Find someone who can ultrasonically clean t hem, then replace all the o rings that have dried out whilst it was sat for 18 months.. there must be someone on here who can do it. happens all the time to bikes left standing.. Quote
Crazy88 Posted October 13, 2022 Author Posted October 13, 2022 Cheers,ill have a hunt round for someone. Still may go big bore kit anyway Quote
fatblokeonbandit Posted October 13, 2022 Posted October 13, 2022 dose it smoke like t,his?? This was a carb problem….. Quote
Crazy88 Posted October 13, 2022 Author Posted October 13, 2022 Yes it does smoke like that but gets worse as the engine gets warm....the shop said it filled the plsce with exhaust fumes when running Quote
fatblokeonbandit Posted October 13, 2022 Posted October 13, 2022 That was a bike a young lad I k9now had taken to a bike shop, they said the head gasket had gone!!!! he asked on fartbook and was told many times the head gasket had gone!! what had actually happened, was the bike shop who had cleaned the carbs, hadn’t tightened one of the pilot jets, it fell out and poured fuel down number 1 cylinder, lots of smoke, took an hour to fix properly 1 Quote
fatblokeonbandit Posted October 13, 2022 Posted October 13, 2022 Also,the fuel,was pouring down the exhaust and washing the carbon down pipe 1, and dripping out the join it looked like oil, so that is why the expert bike shop said the head gasket was gone!!!! Quote
Crazy88 Posted October 13, 2022 Author Posted October 13, 2022 (edited) When id got it running, cylinder 1 wasnt getting hot, it was also pissing fuel out the hose, so taking it to the shop, they originally said it was a carb issue, so new kits on all the carbs etc but after faffing with it they have now changed it to knackered rings. Prior to it coming off the road it was running fine, just smelt a little lean, but now smokes like a coal fire and wont run above 3k, to me it still sounds carb related but im not technically savvy enough to disagree with the shop, which i find highly irritating.

fatblokeonbandit Posted October 13, 2022 Posted October 13, 2022 How much did the “bike shop” charge you??? Quote
wraith Posted October 13, 2022 Posted October 13, 2022 As above, carbs. If the rings/bores are fu#ked at 22k it's had a very hard life, ask the bike shop what the compression was? That will tell you if the bores etc are fucked. Quote

Sounds like you need to interrogate the bike shop as to why they think rings are the issue. Compression test and leakdown test figures would be a start ? Before you start handing any money over !

Any good shop would at least of done a compression test and good shops are happy for you to ask questions, so if they start trying to fob you off you know they haven't got a clue sadly Quote
Crazy88 Posted October 14, 2022 Author Posted October 14, 2022 (edited) Did interrogate the shop this morning, compression test and leak down was done, one cyclinder was low and the smoke was thick blue..sooo i suppose it can only be one thing Edited October 14, 2022 by Crazy88 Quote
fatblokeonbandit Posted October 14, 2022 Posted October 14, 2022 And this happened whilst sat in garage for 18 months???. Quote
