Sundry Twin Mod & Tweak Items

It seems that many of us are encountering problems with our side stand switches. Often, we may have to put up with running the risk of either grounding out on the side stand (having jumped the side stand switch at the connector behind the left side panel) or riding around with the neutral light on permanently (after bypassing the neutral switch instead). It’s not always clear where the fault may lie until the circuit is tested, though the chances are the side stand switch itself will be the... [Read More]

Removing Baffles - Triumph Bonneville

A frequently asked question about Bonnevilles/T100s is how can I modify my stock mufflers (silencers)? Here are the instructions for removing the rear baffles, drilling the remaining baffles and rejetting tips. Bill T100 initially gave me the instructions and I have added to them based on my and others experiences.

Tools needed:

1 ¼ “ metal hole saw (choose a good one)
Minimum 8” long ¼” metal drill bit
Preferred: ½ in drive drill

The rear baffle is held in place by a rear flange and an inn... [Read More]

Scrambler Mini-Speedometer (and Desert Bars) Retrofit

I think Triumph did a lot of things right on the Scrambler but the speedometer/handlebar clamp combo is a sore spot in my eyes. D9 has been designing and fabricating some incredibly beautiful speedo/tach/ignition mounts using the 2 ¼” diameter mini-gauges but did/does not have a solution for the Scrambler’s speedo pod. I liked the idea of getting rid of the entire pod so the mini-speedometer sold on www.mikesxs.net with the incorporated LED idiot lights was perfect. I used par... [Read More]

Bonneville Rear Wheel Spoke Load-Deflection Evaluation-With Update

Broken spokes on the Bonneville, T100, and Thruxton spoked wheels have led to concerns about how the wheels were designed. I spent way too much time and money and used the skills I learned in 35 years as a rocket scientist to do a computer simulation of how the wheels actually work, based on test data of real spokes tested in the real wheel geometry. The results, conclusions, and what it means to us riders can be found at:

Scrambler Bafflectomy

Scrambler Muffler - Rear Baffle Removal


Over this winter I've enjoyed reading numerous member posts on opening up stock mufflers with a "Bafflectomy". The huge thread
started by kdlutes (with pictures) gave me confidence to go after my Scrambler mufflers. I'm not into loud exhaust, but wanted a deeper
sound that is a little closer to the classic Triumph sound. My hope is that this post will give others looking for a small volume boost the
confidence to take on their own baffles... [Read More]

Scrambler Turn Signal and Taillight Upgrade

Before I did the speedometer pod and handlebar upgrade I discussed in a previous post and blog I wanted to do something about the taillight and turn signals on my Scrambler (wasn’t that taillight originally used on a Yamaha Virago?) The above Lucas style taillight and turn signals available from several aftermarket suppliers did the trick for the rear end but what to do with the front? I did not like the low position of the original turn signals ….

Cartridge Emulators

Emulators

by Dickbender (Darcy)

Firstly, I am in no way associated with Race Tech.
Secondly, this task is reasonably difficult if you are not an experienced DIY mechanic then get a professional to do the job.
Now a little bit of theory. What is a Gold Valve Emulator and how does it work? The best answer for this question is from Race Tech FAQs

Q: I have a bike with damping rod type forks. I have heard that Gold Valve® Cartridge Emulators® are the greatest thing since s... [Read More]

Quieter D&D'S Slip On Exhausts

This info was sent to me by another member (FattRat) but I'll pass it on for everybody.

How to make your extremely loud and raspy D&D'S quieter.

1) remove the baffle from the can.

2) cut all the original packing off and throw it away.

3) get fiberglass exhaust packing material.

4) pack the baffle looser and use wire to hold the fiberglass in place.

5) replace the baffle in the can.

6) repeat steps for the other baffle.

7) the new tone is more mellow and quieter.... [Read More]

OnD Sprint Lowering

1) The objective is to lower the bike and maintain the stock attitude. You want to avoid lowering either end of the bike more than the opposite end.

2) Measure the front and rear stock heights from the floor and record them for future reference.

3) Loosen the swing arm pinch bolt enough to allow the eccentric hub to be rotated.

4) Using the Triumph factor... [Read More]

Dealer Negotiation Tips

Buying a motorcycle may not represent a multi-million dollar deal, nor will it affect world peace or some other significant subject like the environment or our society's economic stability. However, the passion usually starts before you and your new machine hit the pavement. Usually this means that motorcycle purchases in general are more fun - or should be more fun.

This document is to help overcome some mis-perceptions and provide sound advice from those who have purchased many motorcycles in... [Read More]

900 Triple Classic Airbox/Carb Removal

Took some pics during one of my &quot;quick &amp; dirty&quot; jet swaps.
They may helpful to someone removing the airbox or the carbs for the first time. I should state that I am not a mechanic (or that experienced working on a motorcycle for that matter) and these pics are in no way a substitute for a shop manual.

1. Undo the fuel line from the petcock (make sure the fuel is OFF, it's on in this pic!)
