as you can tell by the title i am new to the nsr world. yes, thank you for welcoming me with open arms!
lol. anyway, ive been off and on about the nsr for the past 3 years. but i think ive come to terms with it and im going to try buy one and import an mc28 into Canada for next year. (we have a rule it must be 15 years old or older to import) so yeah as you can see i've waited this lengthy time frame out to import an mc28. now to only find an early 94 model 
in any case, im just wondering what the common problems are with these bikes. also, i haven't seen TOO many parts widely available here locally or even within Canada. are parts hard to come by (either here or USA)? ive also noticed alot of people talk about "nsr tuners". is it appropriate to take the bike to a strictly 2-stroke or "nsr tuner" for maintence and upgrades? or is general maintanence and upgrades easy enough to do on ones own?
any help would be greatly appreciated!
