Just a guess........

If the valves are set correctly...........and cylinder compression is good.....maybe an exhaust leak or a head gasket leak..........just a guess. Let us know what you find......
Good luck on resolving your problem............

My 2 cents.........

I ask, not as I am trying to cut corners on my build, but trying to understand acceptable alternatives that achieve a similar setup. I understand that if you raise height, you decrease center to center geometry on the bike, which in turn can make the bike twitchier in corners, and I am OK with that issue.

Thanks...

I think you are on the right track............contact Rick at Cogent Dynamics.....he knows suspension, set mine up with xr600 forks with racetech valves and built me a long travel Moab shock for my TA...........makes a miraculous difference.
I think his website is motocd.com...........

Clockwatcher thank you! I have the front end covered thanks to a member on the site (just need to work out the final details) so your input is fantastic. I will contact him tomorrow and see if we can start a dialog on developing an option for what I am trying to accomplish. The fun thing and curse about building bikes is there are a million and one options you can use. I learned a long time ago, when you find something that works or meets your needs, go with it! Analyzing something to death can lead to vapor lock on a project and while I have some time to work on this, I want to spend more time riding than building. .

Reading a bit old posts... RD03 swing with stock TA shock (also 375mm) gave me 45mm more height in rear. I think, with RD04 arm should be even a bit more as it is longer than RD03 swing.

Spent the better part of Sunday afternoon reading this thread. I had hoped to be to the end by Thanksgiving...(Currently at post 4100). I am finding that this build of mine is taking on a life on of its own because of this thread and all of you.

Most bikes I work on are newer in nature so there is not a lot of information on what you can/can't do to them. Yet with the TA, the Mod thread is like going through a history book seeing all the work that people have done. But it does not stop there, the human factor is incredible and the trials and tribulations and even the passing of some members draws you into a very extended and wide family history. So many times I am tempted to respond to a question or comment but I have to stop myself as they were asked and answered 7 years ago. So as I work my way to the present day section of the thread I find that I am beginning to weave myself into a very long linage of riders and builders who are really paving the way for the new owners like myself. I hope my efforts to copy the work they have done, does them justice. Thank you all for what you have done, I look forward to what will be down the road.

Here is where we ended yesterday, the Givi bags are off and the few parts that are in are being laid out.

I did the same thing when I got my TA. For thoes of us into this stuff, it's like a good book you can't put down. It was interesting to trace the migration of individual bikes from new owner to new owner and the changes they made. Also the coming and going of owners as their needs/wants change. Some members have greater knowledge/experience in one area and others in different areas, most are very helpful with answering questions even if they have been answered many times before. It's unfortunate that many of the the early pictures have been "dropped" , and there is no assurance that recent pictures will endure. I have a very disorganized set of notes/references, and save or print things I want to keep. Looking forward to watching yours and others continuing interpretations.

Having gotten to know Dr. E through several emails I can tell you he's the right guy for such an undertaking. His mechanical experience and attitude will make this a fun project for all of us to enjoy and learn from.

There is a wealth of knowledge in everyone here so feel free to ask any questions.

Engine Guards for an '87

I can't seem to find a vendor with any Givi engine guards in stock... Motorcycle Superstore showed on-line inventory available but none in reaity - and they are saying Givi won't give them a date on when they'll have any ready for shipping. I've just put a request in the flea market in case anyone has a set for sale or knows of someone who does.

I'd be surprised if anyone really stocks them anymore. I ordered from sporttour under the same deal (they didn't know how long it would take Givi to get them made) and got them in two weeks. This was just a couple months ago.

I got mine here:
http://www.happy-trail.com/Products/..._GIVTN363.aspx

They mention a modification needed to mount this guard. You may already know but the only modification really is that you need a longer bolt for the front engine mount than the one they include. It seems like the length needed isn't easy to find in the right metric size so most folks, including me, use a 5/16" bolt in the correct length instead, which works just fine.

Thank you JB and APP... Happy Trails called Givi for me while I was on the phone and discovered the last one in North America was sitting in Charlotte NC - on it's way to Dartmouth now

If anyone else needs a set, twisted throttle's website shows they have some in stock also. Usually pretty accurate.

Fork/triple swap

I can't remember and I didn't flag it. Anyone know if an '87 xr600 triple/forks will mate up to the '89 Transalp? an Inmate is selling a set, not sure I am ready to do it but just in case.......

I just picked up a highly modified 89 Transalp, Yes the one Jim has show earlier in this thread. But my real question is does anyone have any advice on side rack for the bike ? It has a big Hayabusa muffler on it and while it does not look the best it sure is light, sounds good, and runs great. I do not know if this would interfere with a stock type side racks or not.

open to suggestions.

Marc
