When I bought my tooned 900 18 months ago, I knew what Brian 562 had done to it - a lot of money went to TTS Tuning Shop and a fine job was done. Thye first time I rode it it was on 2 teeth larger rear sprox than standard and the way the thing accelerated blew me away - violent wheelies in first and second. Fine for Brian at around half again my weight but OTT for me - I changed back to standard and it was still seriously quick.
I stored it over winter '06 and when I first started it up after a 3 month layof the feckin' camchain rattled like a machine gun for 2/3 minutes. I setup the crank on "T" and adjusted the chain tension. I heard a "clunk" and assumed it was adjusted ok. The noise came back once in a blue moon.
The bike was going well but at the RTT in July '06 I was surprised to have to run pretty hard to stay with Hartside Man's fairly standard 900 (didn't tell anyone of course - especially when Brian had spent over £2k on the motor )
When over in CZ Republic with Dapleb the chain started to get noisy again - bad enough to want to try to adjust it again in Grandma Zundapp's back yard. As documented in Dapleb's excellent BLOG I adjusted it again and this time a hooge "CLUNK" told me it was more than the tensioner - the feckin' inlet cam had sprung back 3 teeth. Dappers and I worked by headtorch and no manual to reset the cams and the following morning I gave it a good blast. It was going good but seemed to run out of puff - short shifting seemed a better way of getting past the Power Ranger on the 600. Then the TPS started to give problems (probably caused by the dusty conditions getting crap past the seal)
Youse still awake?????????
To cut the story short I felt maybe the valves might need readjusting since the cams had been reground by Kent and that was why the engine felt less sharp................that would be a winter job I thought.......aye right.......never happened!
As mentioned on another thread about camchain tensioners, I had the bike MOTed on Friday and the helpful mechanic thought he would do a dodge to set the tensioner that he'd done on loads of R6s..........you've guessed it "CLAAAAAAAANNG"..........Feckin' cam jumped again We reset it and today I took her out for a the first run of the year.........JEEEBUS...........the "old" bike is back..............feckin' rocketship again.......front wheel pawing at a half throttle in 1st at 4000 rpm - pulling hard at 2000 in ANY gear....................
The inlet cam must have slipped 1 tooth at that first tensioner adjustment way back a year ago and thats why it was a wee bit "flat", I certainly must've set it a toth out by candlelight in Grandma's yard.............Robelst mentioned a while back that he thought his valve timing was out - these engines can run a tooth out - and fairly well at that!
It's really like having a new bike again - 5000 in 6th and open up full and it just storms up to 120 + in no time..........soooooo much quicker than before - like it was when I first rode it...........sharper bark from the CCC silencers and less popping on the overrun.
Hope you're all asleep now...........
