new track time

[bandet01]

well guys i just got back from the track and got the best that the bike has ran to day and it still has more in her. she went a 13.282 @ 99.40 and that was will me on it and i weight 260 and the only thing that got changed today was the clutch adjustment everything eles was like i ran it a few weeks ago

a couple guys there where telling me if i got aftermarket exhaust with the baffles back in it, it would go faster. what aftermarket exhaust would you use but i want 4 into 2 not a 4 into 1

second they said changing the coils would help and rejetting the carbs

third is there a company that makes gears or complete rearend for the xs

[chevy45412001]

right on

good job you lost 6 tenths. with just a clutch adjust good deal. i ran my best with a 4-1 no baffles (thats how i got the bike so not sure with baffles) stock jetts for the xj were 112,now running 137.5 with no air box 4 pod filters. I did remove them also good for 2 hundredths more but no more mph.

hey chevy45412001, what's your best time and mph on your xs11?

[Port V.P.]

Look into a vmax rear end! and accel makes a great coil kit, doubles your stock output volts at the plugs. You will have to regap your plugs to a minimum of 35 thou. and you can go to a hotter plug NGK BP5ES
and hang on !

Hey gnepig

I run the younger brother XJ11. Best to date for me is a 13.10 at 102mph. Thats at great lakes dragway in Union Grove Wisconsin (not sure of elevation or lack of. not really sure it matters.) That is slipping the clutch bad to get off the line.60 foot times are very bad in the 1.5 to 2 sec. range.

[bandet01]

i was planning on running the accel coil kit anmd thanks on the number for a hotter plug and my best 60 foot time was a 1.880


does anybody know if the v max rearend is a direct bolt in

[Port V.P.]

Call up your local Yamadog shop and cross reference the parts numbers!
I think they are
if not, the guy I knew swapped out the complete swing arm assem. 'cause he wanted to put in a bigger tire or slick on and it wouldn't go with the XS rear end. And if memory serves me right it looked weird because the rear tire sat offset to keep the shaft as straight or true as possible. This is going back... geez 20 or 21 years ago

One of moderators is incredibly knowledgeable about Vmax's amongst many bikes. That's are own Mike Hart (hi Mike, when you coming back to the island for a visit?) I recommend you pick his brain about it!

Accel coils

Do you happen to have the part numbers for those Accel coil? Also, is there a better after market voltage regulator for the XS, and would it help with lights, etc. My bike starts strong with no problem, and it doesn't seem to have a battery problem, but it also doesn't seem to be strong enough to make the turn signals flash at idle. You have to rev to about 1500 RPM's to get enough output for it. I suppose it could be wiring issues also, really haven't looked into it, but with the mention of the coils I wondered if it could also be old equipment. I have seen new fuse boxes and such online for the bike.

[Port V.P.]

I got my coils from Dennis Kirk online, but mine were for an '81 or XJ. If your bike is older, you'll need the 1.5 ohm set. as for electrical gremmlins... clean your fuses and fuse holders with a fine emery, check your grounds and clean your connections with a good electrical contact cleaner.

The only thing that was notorious with the XS's was their poor output from the alternator (low amperage) short of having an expensive rewind at a shop there isn't much you can do about this.

Check and clean all your connections throughout your wiring harness and it will clear up a lot of little gremlins including weak spark and proper functioning, pull those connectors apart and have a look they are 20 + years old ya know

If I remeber right Pat Kelly installed a set of Dyna hi performance coils in his $60 gem (NICE BIKE) and he was amazed at the difference in performance.

Check out www.denniskirk.com and look for the dual post coils, sets mine came with nice fat yellow 8.8 hi-tension sparkplug leads, and boots

I just went down to my bike shop and found the box and invoice:
Dennis kirks part # 20-309 (super coil kit / accel)
Accel part # 140403

Ask Pat if you want to know about the Dyna's,
Hope this helps you out .

Thanks

I have shopped with DennisKirk already, so I think I'll order those coils. Maybe during the winter when I take a week or so off riding I'll pull everything off and clean and check all the electrical stuff. Thanks for the advice.

[Port V.P.]

a week or so off riding.... must be nice

Up here where I live (and it's the mildest part of canada) I take the bike off the road from mid october until the beginning of april, it's just too wet and too damn cold

...could be worse though, I could be living near my sister in Anchorage Alaska

keep the shiny side up,

Hardcore

Most people park theres around here too, but mine is my primary mode of transportation, so I ride it unless it is a downpour. Then sometimes. Wife has a cage, daughter has a cage, so we can manuveur around if we have to, but I prefer the bike. Just moved to GA, so I don't know about the winters, but 200 miles away in NC where I came from the average in the winter time was in the low to mid 20's, sometimes dipping near the 0 point and staying for days, but not too wet. Gear takes care of the cold, but cold and wet is unacceptable. If I took mine off the road for a week it would be because I was working on it, and winter is the best time. Not nearly as fun riding as it is in the summer.

Hey Sermn8ter,

The Accel's are a bit pricey, at $163.00 for a pair of dual output coils. The # he posted is the 3.0 ohm style for Inductive Ignitions, they don't have a 1.5 ohm version so you just need to bypass the ballast resistor so that they get the full 12 volts worth.

Dyna makes a 1.5ohm version!
There are several tech tips on coils you can check out!

I have an Accel coil on one of my 650s. They have all this bs in the instructions about how the spark is so hot you've got to open the gap in the plugs and re-jet your carbs. This is a load of malarkey. My ohmmeter readings on the primary and secondary windings were identical to a good stock coil. The Accel coil may be more rugged but I doubt if there's a performance difference, I was unable to detect any. If I had it to do over again I'd just order from mikes xs.

[Pat Kelly]

When I put the Dyna coils on my E I also switched to Bosch Platinum plugs.
I posted that the bike had more power. I have no numbes to back that up. It as purely seat of the pants feel. I do know that the bike wouldn't hold the front wheel 6" in the air for 100' before but sure would after.
