As part of my plan to do all my own servicing i've stripped the bike down to check the valve clearances and unfortunately all six exhaust valves are outside the tolerance (all tight). If i'm honest it was more work than i expected just to get to the this stage, the amount of things to disconnect or remove and everything crammed is a tight space, i'm now wondering if i've reached the limit of my confidence and competence and i think removing the camshafts and re-shimming might be a step too far for me, given the consequences of a mistake. The service manual shows two different triumph tools are needed to keep the camshaft timing (a timing plate and pin), is it safe or even possible to do the job without these tools? Ideally i'd like to do it myself and if i had the triumph tools and someone to walk me through it first time i probably would. I've fired off an email to muddysump but not sure if he would even do the valve clearances on their own with the bike already stripped?, always seems to be booked up anyway. The clearances range from 0.290 up to 0.320mm with the limit being 0.325-0.375mm, i know its hard to say but do you think these clearances will be causing any issues as yet being as they are only 0.035mm tight at worst, 10% of the total clearance, the bike currently is on 18,000miles. Do people normally get away with re-using the cam cover gasket, the manual says to replace but as its a thick rubber seal and in good nick will it be ok to re-fit Sorry for all the questions but i know there's some good engine guys on here.
