Re: Revived VTR - Trying to sort out 4k vibration
With the upper cylinder cleaner, as some of it is likely to have leaked past the rings, do you now need to do an oil change? I'd say if you followed the advice on the can and just let it sit two minutes before purging it you'd be fine, but I let it soak for about an hour so I'm guessing some would ...

Re: Revived VTR - Trying to sort out 4k vibration
*** UPDATE *** Was a bit of a delay while waiting for parts from Japan but in the mean time I popped the valves and took a look. Both exhaust valves had slightly leaking seals, though one worse than the other. A bit of freeplay in the guides but nothing alarming. Intake valves were clean and tight ...

Re: Revived VTR - Trying to sort out 4k vibration
Righto, stuck into the rear tonight. Rechecked the compression this time on a cold engine and got 160 front and 138 rear, so still a reasonable variance. Pulled the valve cover and checked the timing and clearances first, all spot on. Next was pop the head off. Noticed some lettering, pen markings ...

Re: SPRING RATE CALCULATOR
Sticky so figured I'm not reviving a dead thread. At 73kg (11.5 stone) I was wondering why I had to run minimum preload on the rear and maximum preload on the front to get proper sag. Makes sense now I have the actual springs rates. Why would Honda go so squishy on the front? Surely the "engineers ...

Re: Revived VTR - Trying to sort out 4k vibration
Probably worth doing, if you're not fed up with the damned thing at present. Definitely not fed up at all 8) I bought the bike as a project and to up my skillset which it has done. This is just another challenge. I have two other fully working bikes (XSR700 converted into a dirt/adventure bike and ...

Re: Revived VTR - Trying to sort out 4k vibration
Cheers for the tips and following along. Valve clearances were all checked and adjusted (front and rear) when I reset the timing. Rear and front pot needed one intake shimmed each but that was it. I'll recheck the rear as soon as I pop the cover off just to be sure though I was pretty thorough with ...

Re: Revived VTR - Trying to sort out 4k vibration
The plot thickens! Ran the compression test on a warm engine about an hour after getting home from a ride. Ended up pulling 170psi on the front (the one I just fixed) but only 145psi on the rear. I checked multiple times, swapping back between the two each time and got identical results. Tried the ...

Re: Oberon Clutch Slave Leaking
OK, well hmm, I may order one, I have a leak on my slave, which is weird: 1) it lost all the fluid out of the slave whilst stood on the workbench for 1 week. 2) Refilled and bled with a vacuum bleeder and it did exactly as others have described, nothing, nothing, nothing, then bang fully bled! 3 ...

Re: Revived VTR - Trying to sort out 4k vibration
Lastly, have you tried slackening off all the frame to engine mounts except the long one, then retorquing them? Gave this one a proper good go today. Fashioned up 4-pronged socket and loosened all engine mounting bolts then retorqued all six positions (front, middle, rear - left and right) per the ...

Re: Oil Feed Mod for Auto CCT?
From my understanding, the oil feed mod (if there is/was one) would only prolong the failure of the spring so still isn't failsafe. I performed the stopper mod on my new front tensioner (previous one failed) and original rear tensioner (hasn't failed... yet...) so at least when the spring goes bang ...

Re: Serious Misfire No Power
Mine had the popping and farting the first time I got the bike up and running, so bad that it kept shooting off the rubber cap that was pressed onto the vacuum port under the front intake on the engine. Once I reset the TPS to 500ohm and balanced the carbs it vanished completely. You'll need a ...

Re: Revived VTR - Trying to sort out 4k vibration
One other point to note is that, often, people try to use the engine at low revs and it's lumpy that way. Mostly when people are used to an il4 and try to open the throttle hard at less than 3k. Sometimes its the drive chain being adjusted wrongly. Adjust the free play to 20mm with a person the ...

Re: Revived VTR - Trying to sort out 4k vibration
Where are you feeling the vibration? Through the bars, the seat or generally? And is the vibration in all gears, or just top? Vibes are felt across the whole bike. Feels like the engine transmitting it across the chassis. All gears, right on about 4200rpm when throttle is above about 50%. Perfectly ...

Revived VTR - Trying to sort out 4k vibration
Hi all. I recently aquired (for very cheap) a very tidy 2002 VTR1000 with a suspected front CCT failure. 40k (km) on the clock. Decided to take on the project and lucky me, ended up being 2 slightly bent exhaust valves with no further damage. Purchased new exhaust valves, new stock CCT, new head ...
