i sent my bigbore off to grampian about 2 weeks ago i got a call on tuesday from the bloke whos has an account with them and they said they wouldnt fit a blaster piston to it because it was on its limit, thie bore size is 66.65mm at the top so why could a blaster piston not be fitted ?? im not happy it cost me £16 in postage there and back, does anyone know where else i can get it done and howmuch it would cost i think someone said about norbo being able to get that stuff done ?? help needed  |

Iv used Grampian for years, im thinking they know the game by now. ive also heard very good things about grampian motors.standard big bore is 66mm so perhaps they wasnt aware what piston to fit,personaly if your bore is repairable get it rebored localy and measured by the place that dou your rebore and ask them to fit a oversize piston kit for a aircooled dt175. im guessing that because you asked to have a blaster piston fitted it would of involved fitting a even bigger liner as a blaster is 200cc,im not 100% sure on this because i havent seen your barrel but thevdt piston is the way to go if the bore is servicable. ps i sent your seat catch today  |

if the bore isnt badly scored a 1mm or 1.5mm rebore and a decent dt175 piston kit will get it working,have you got a copper head gasget and a rd400 little end bearing?
if the liner is beond repair a new liner can be fitted but it wont be cheap

hi twostroker i just sent you a pm i about all this you must have been postin as i was sendin the pm lol i would get it reboured localy but i live in (the land of funny spelling lmao) anglesey if you buy a bike round, say a bolt has snapped it wont be replace it will just attaked by some farmer with a welder the closest place is grampian.
i must have got confused with the blaster/dt somehow my head is pretty mashed by the wholething lol id nevr even touched an angine till about a year and a half ago, yer iv got a copper gastket and a decent homemade one that i got with another bigbore the liner is in good condition no scores just it was covered with fluffy surface rust and had ally smeared on it, thanks for your help mate
