I am currently researching GL1500 as I am thinking about buying one.I have found alot of interesting info on this site but very little on performance upgrades.Are there few aftermarket parts (pipes/cams/etc) or am I just missing them?

How fat is your wallet? :cooldevil:

After market exhaust are the most common and widely available items, while turbo/super chargers are available on a custom build basis.

A well maintained 1500 will have enough performance for 98% of owners. If not, then perhaps you should be looking at a sport tourer, rather than a full blown touring bike?

BJfunbear, welcome to the forum.

To answer your question, YES, there are performance options for the GL1500.

There's a 4*advance triggerwheel,

fPartsQ5fAccessories.


Then I've seen "torque Tubes, which replace the header pipes & claim up to 30 HP increase.


I bought a 1997 1500 in July of this year, & believe me, it will go fast, FAST. It willcruise at 95mph all day, two up. When I do my timing belts this winter I plan to go with the trigger wheel. I do believe the hp gain with the exhaust is way too optimistic.
Feel free to contact me if I can be of further assistance....-Rich

Dont forget the E3 diamond spark plugs, at least 3 hp gain. Carb tweaking is another biggie, bigger jets n stuff.

LMAO... start with exhaust system and rejetting, spark plug tip above is another good upgrade that I have learned but not had time to try yet. Advance trigger is on my list as well.

Cant find it now but had an article book marked from a blog... guy installed a 50 shot NOS system on his 1500, supposedly you can have an intake injector machined and spray into the mix at 30% for around a 30HP boost when pulling loads up hills or passing etc... NOT recommended for high RPM application

YUP there it is in fact ... there were two of those with braided steel running to a bottle in the trunk and a digital controller mouted on the handle bars



May seem a bit extreme but the engine is supposed to be able to take it no problem and 30 HP is A LOT more muscle when you need it than anyone may really realize.



Maybe a 350 dollar upgrade? 30 HP at the rear wheel for less that the cost of good quality slip on mufflers.





WOW

I have put the 4 degree trigger and the Torque monster pipes that replace the exhaust unit and make it true duals. It makes nice noises without being loud. I can't really see a big difference in performance and the mileage doesn't seem to have changed. I am going to try a set of Macs mufflers next. If I don't like the noise I can always go back to the stock pieces. The 4 degree wheel did stop the stumble off idle so it was worthwhile without a performance gain. I understand that the later 1500s don't need this.(mines an 89) I know there are people here on the website that can tell you what years.
Admittedly I have done no tests to check performance so this is just my opinion.

N2O is great, but dangerous on a bike for a first-time user IMO... not to mention it is a active power-adder.

Turbo-charging is a passive system, and less dangerous than N2O in all aspects for a motorcycle (unless it is a straight-track bike) and still supplies a level of risk... again, IMO.

Although I've never done either to a bike, I've had a few vehicles that were turbo-equipped, one with N2O in addition.

My'93 Olds Achieva with a Quad-4 and T-3 Turbo was nothing to sneeze at on I-10 between Phoenix and Tuscon, and was my favorite.My '87 Grand National w/N2O to supplement lag spoke for itself with no denial accepted, and my '73 Vega w/ a stroked SB400 and using a 2-stage N2O set-up died from a thrown rod tantrum of a fit one clear night at Budds Creek in Md. (Isold it and built my XL).

I would have to change (read: adapt)every riding characteristic I've ever learned to safely ride a bike with either power-adder.... but that's me, and I'm certain I could master the art of one, or both.


Edit: based on my expierence, you would NEVER want to activate your N2O system unless at WOT... For a bike, to me, that translates into a straight-track-only app.

Most likely I would maybe put on some pipes and retune the carbs at most .I Do not want to compromise the reliability as it is a tourer and not a sporty bike.I used to have a 78 trans am we dropped a 396 with N20 into ..loads of fun.
