Hi
Does anyone have a link to any sites that show you how to internally lower front forks?
I know there was a thread here somewhere to an American forum where a guy showed how he did it and people where giving him shit about it.
I need to lower a set of TZR250 front forks for a Drag bike.
Thanks
Richard
For whom the bell tolls
I believe a common way to do it is to use a fork strap, similar to a tie down strap, to compress the forks. Another way is to raise the forks through the clamps, thus lowering the front end without fucking up the internal function of the forks.

where opinion holds more weight than fact.
It's better to not pass and know that you could have than to pass and find out that you can't. Wait for the straight.

Those forks are damper rod forks. I have installed lowering kits on some cruising bikes that also use damper rod forks and they either gave you longer top out springs or a spacer to use with the stock top out spring.
If you shorten the travel this way you need to also need to adjust the spring preload spacer length accordingly.

Depends what model TZR. Last ones were cartridge uSDs. Actually so were (most) 3MAs. But yeah a spacer is used. Might want to run stiffer springs else you'll be bottoming out & depending on how rough when you land the wheel would be nice to have some movement.
Don't you look at my accountant.

As per the two replies immediately preceding this one

Hi
Thanks for all the replies but I still don't have a link to either the thread about how it is done or a site that will show me.
This set of forks is not a cartridge set so it should be easy to do once I find a "How to..."
Thanks

On the surface its a semmingly simple job but there are a number of traps that can make or break the job. Send it to a proffessional to do.

Hi
Thanks for trying to help me not make any mistakes but as I have built my entire drag bike by hand I'm quite confident that I could handle this
job .
Thanks

Goes something like this no? (But with better understanding of what does what and things to avoid)

To not put too fine a point on it for me to describe this to you inclusive of all the precautions , whys and wherefores its a LOT of typing. Personally I have a record of not at all being averse to helping people but theres a limit and constraints on time, plus its also giving hard earned knowledge away. Thats always a fine line.

Hi Richard, Im no suspension guru, but I have just modified a set of TZR250 1KT forks for a different purpose. the preload spacer is sitting on top of the spring and is 95mm long. underneath the damper piston is a short spring which stops the forks klunking when fully extended, what the other guys are suggesting is shorten the top spacer and move a similar amount to space the short spring. Im sure there is some other technical stuff that you may need to deal with, but looking at your site I dont think you will have too many problems.

Hi
Thanks for the info.
Ora Et Labora....our family motto from hundreds of years ago in Scotland.
I do none of the first bit and as little as possible of the second bit.
Thanks

Hi
Totally understand...Time is money and so is your knowledge and there are always limits to how much of each you can give away.
Thanks for trying to help anyway.
Thanks
