Henders doesn't mean the chain guard, but the chain block - what the Triumph fiche calls the rubbing strip. It's the plastic piece that wraps around and protects the forward part of the swing arm from the chain.
Henders is right, when you deflect the lower run of the chain upwards by lifting it with your finger, it hits the bottom of the chain block. But you can still measure chain deflection despite that.
I place a rule at the midpoint, and then rotate the wheel until the chain is at its lowest point on the rule (loosest). Then I lift up the chain at that point to measure deflection. Yes, the chain will hit the block but you can still lift the chain until you measure total deflection. Like others on this forum, I tend to go to the top of the acceptable range - a loose chain is better than a tight chain for wear and tear as well as driveability.
I was contemplating this myself or least what is free-play. deflecting the chain as much as possible or gently raising it from its resting position until you are no longer taking up the slack. I suspect it is the latter but have not been able to confirm it. here is some of what I have come across:
there are a few helpful threads on this site. I could not find the one I was looking for(guy was a bike mechanic). He suggested majority of user maintained bikes had chains that you could bounce a quarter off of (Paraphrasing of course) however jist of it was to suggest putting a heavy person on the bike to press the sprockets to a horizontal alignment. Like it is when ridden. Presumably maximizing accuracy of the tight measurement.
Allowing for the arcuate motion of the swinging arm, the tightest point of the chain is when the gearbox sprocket, swinging arm pivot and rear axle are in a straight line. I get my son to bounce up and down on the seat to check my adjustment.
unlike some things in life, it's better slack than tight.
The chain will be at it's tightest when the gearbox sprocket and rear axle are as far apart as they can go (within the range of suspension movement) which is when they are in a straight line with the swinging arm pivot.
well, after reading all the threads about fitting 600 coil sticks in place of the gills it seems that most threads ended inconclusively except one or two on the tigers so i thought what the hell, its winter and the bike is in the garage so i have ordered a set off ebay to try for myself, cost...
I took my carbs off for cleaning as it was sitting for over a year and bike wouldn’t start.
One things that bothers me is that there are total of 4 shins under needles, is t this a lot? I tried looking to see what jet sizes are in it but numbers are so tiny that I can’t see what they...
This year I will begin using my 2000 Thunderbird as my touring machine. The '96 Sprint that I've been using all these years came with Givi hard bags that hold a lot, are absolutely water-tight, and are also very very ugly. Does anyone have a brand or model of bags that will fit on...
I've had my 2000 Legend for 15yrs and I'm feeling the itch for something new. I've been considering a used or new Street Triple. If you were to replace your Legend/Adventurer what would you choose from the Triumph line-up?
Hey there -
Long time triumph owner (2016 speed triple R), and about to pick up a 1999 Thunderbird Sport. Have always loved the TBS triple, and lots to learn.
One immediate question. The bike I am interested in seems to have a slight bend in the handlebar. Seems the previous owner dropped it...
