Re: How to Wake Up a 1975 r90/6?

I'd replace the gas line. I've been told the weaved stuff isn't as good as modern fuel line. ► Agreed. The ethanol now in the fuel will make the older fuel line deteriorate rapidly. You'll be forced to replace it within the first 6 months for one reason or another. The newest fuel line is usually s...

Re: Redline Heavy ShockProof Gear Oil worth the cash?

Incorrect. Changing low mile use gear oil every 6 month, unless there is a moisture incursion , would be flushing money down the commode. Thank you. You've made my point for me !! How can you possibly know there's no water in there without draining it ? And once it's drained, it's silly to put it b...

Re: R75/5 fork drain problem. yikes!

On my '79 /7 forks... the 13mm hex nut is removed completely. Then the 4mm Allen wrench is used to push the bolt up until it rests on an (unseen, but felt) internal step. You must push very hard against the fork spring to accomplish this. Some minor amount of oil will dribble out at this stage. With...

Re: Redline Heavy ShockProof Gear Oil worth the cash?

► One of the advantages that you'll see prominently touted of high-priced oil is that it lasts so much longer, therefore it is worth the extra cost becasue you'll be changing your oil one-third as often. That may be true for cars and trucks in daily use, but it may not apply to motorcycles . Motorcy...

Re: How to Wake Up a 1975 r90/6?

Welcome to Airheads !! No clue as to what your location might be, so it's not clear if you have another 3 months sitting around and tinkering (Michigan), or seriously ready to ride right now (Arizona) ? In the intervening time some things have drastically changed... fuel for the worse , and oil for...

Re: UTT Master Cylinder pressure light

One short hose MC to splitter, two longer hoses to the calipers. Crush washers. Or, 2 very long hoses and a double-length banjo bolt. In the USA we have on-line stores that sell race car parts ( Summit Auto , Race Part Solutions , etc). One of the product lines they typically sell is Teflon (PTFE) ...

Re: UTT Master Cylinder pressure light

I have disassembled the m/c and the bore is pitted to perhaps .5mm. I had to knock the piston out from the other end such was the corrosion around the circlip end but that cleaned up ok. This is typical becasue the only "standing water" was inside the brake system. You can't trust a used Ebay part,...

Re: r100 81 fork

I concur. The place to start is with the fork stanchions not being absolutely parallel. A minor bump could twist the fork assembly in such a way that the wheel does not steer where the bars are pointed. That is to say maybe 1º or 2º either to the left or right. That can be caused by a simple pot hol...

Re: Monolever fork nut stuck

The big (34mm ??) stanchion tube caps typically get stuck when novice mechanics decide it's a great idea to put some thread sealer on there after a fork oil change. It is not a good idea. The fork oil never ventures that high and the residue can only make getting the cap off much harder the next time.
