Tuner says its ok to bore to 54mm one thing i did ask him as i was a bit concerned at the stepped landing only being 1.5mm thick was to have Hindle reman, submerged weld the bottom and then turn down so a thicker bottom land would ensue, dave said that probably the cost for this would be greater than haveing new liners made i enqured at the price of them and the company who makes them for him befor he machines them down ar

as you all know i,m doing a 400-4 cafe/racer well the saga continues, one thing as you seen from does 4 liners etc Ive found a suppler that can do 54mm hi comp pistons Honda say don't bore out more than 1mm but liners seem to have plenty of meat to out to 54mm this leaves the stepped land at the bottom with a 1.5mm sidewall, depending on what the chappie thats going to be gas flowing heads crank lightened balanced etc if doable would be a 458cc Joby also got clutch parts back and are better than Honda new cost a bit though and having a custom billet cover made for generator is so far

Why not just apply a carranubba wax and not polish it up. not done it on a bike but used on cars....... come spring good old wash off and bit of elbow greaes then put on the sun gogs as shine will blow you away .............. and silica crystals will take out moister in the air .

aquablasting is the best for alloy.look for anyone local to you who do it .........one thing to ask is 1, do they use the bio-degrable liquid in the prosses and 2 do they blow out all oilways/blind therads etc etc..

years ago there were many many plethora of bearings than there are today.....most post 90,s seem to be made for application ie the part to a standardized bearing, although a GOOD bearing stockist will have a cross cat that can mix a 2 or 3 part bearings to suit.....even using sleeves
long gone are the times you could get anything from 30 degree to a 70 degree annular outer/inner from different manufacturers and find a spot on one.

could be a broken or about to break inner drive cable or one of the flexible coils have opened/broke causing it to stick in the sleeve cover of cable. also look into the rev unit to see if the square drive input isnt broken ie one edge split.......

You can't get them from a bearing supplier as the outer race is ground special to fit
not quite,,,,,, back when i had to source them it used a british imperial top bearing and a iso metric for bottom..... good old british timken...... and steve, i cant say from my experiance what its used for or where it goes but perhaps the following may help you determin where it goes............... when i did mine getting the lower headstock inner race off, entailed starting it by hitting the lower washer with seal this wasnt a problem in the 70,s as replacement parts were still available, if the "hole" in the washer will fit over the larger lower bearing land then it may be a replacement for this.......if its inner diamiter will fit over and its outer is 50mm then it could ,depending on how deep the inner race wall is to be a spacer before inner race is fitted.......on ds site it looks a fair old washer....... so without doing it i cant say 100% where it goes perhaps someone else has done it with the ds bearings or give em a ring and check before fitting..................

the ammount of engines ive seen been fire damadged by wrapped exhausts could fill a book, exposed they can get contaminated by oil, desiel, petrol,......... soaks into wrap............ nice hot exhaust and bingo a fire, only 2 things id put on mild steel exhausts is, 1 vht paint.....2 a sprayed ceramic coating but 2 is going a bit overboard as is expensive, but if you want to thrash your bike then hold one of the headers then ceramic coatings the way to go...........................
