Hilltopped yesterday

[LBL]

I went up to Geoff yesterday to try to sort my terrible surging as low revs, it made my town riding a real pain.

My thoughts.

Made the ride home filtering and stuck in constant traffic on the M1 better all joking aside, called Geoff in the morning and he said come up today as ive a free spot, im happy with the result but will hit the twisties this weekend to get a better feel, can certainly feel the extra BHP on acceleration but tbh its only the smoother delivery i was after

Sounds similar to my experience. TBH, who needs more than 100 bhp at the back wheel anyway. For me it was the low speed (low revs, high gear) running around town that I wanted addressing and it was a great success

Anyone aware of someone 'oop North' that can do a similar job?

 

[xantamisch]

what figures did you get out of interest?

thanks

Paul at Dynobike in Malton has a very good reputation,although I believe he uses Power commander rather than a remap.

I had my Tuono sorted by Paul, he did a cracking job, but I'm not aware that he can re-map existing ECUs.

TBH im not really one who thinks its makes that much difference because its impossible to use in everyday life, but BHP was up 20bhp from 85 and torque was up from 74 to 88. more importantly as ive got an aftermarket can it was running very lean and the remap sorted that out too.

85 bhp standard sounds like something was wrong to me?

Hey LBL

Does the bike behave better now at lower revs? The old Hexhead used to chug along and was difficult to stall. It dug real deep. The WC does not dig deep, and stalls very easily. i'm led to believe thats because the bike runs very lean. Does the Hilltop map sort this out?

With my 2013 LC Geoff got the following results:

The initial dyno run certainly made interesting viewing/ready. Max power at the back wheel was 97 bhp at 7648rpm and max torque was 73 ftlb at 5900 rpm - nothing to complain about there. But looking at the lower reaches of the power and torque curves highlighted why I was standing there watching my bike on Geoff's dyno: below 4000 rpm the curves looked like the back of a particularly nasty crocodile and were clearly the cause of the uneven running that I hoped to improve on or correct.

Anyway, after Geoff's computer software had done its work, I ended up with lovely smooth power and torque curves with a max power of 114bhp at 7470 rpm and max torque of 90 ftlb at 6120 rpm. But, to my mind those increases were no more than a by-product. The important change was that now, below 4000 rpm, I got smooth power and torque curves.

Hi mike,
Yes I was having the same problem, I took the bike out yesterday to test the same thing and it's much better at lower revs, I tried a few very low speed 3rd and 4th gear pull aways from very low speed at got a bit of chugging but then quickly into acceleration. It does still surge slightly but it's much improved in town.

IMHO it's not a miracle cure but has made the ride much more enjoyable.

85 on an lc?,doesnt sound right my 2013 gsa hexhead recorded 85 on the initial run and 103 after mapping.

can anyone explain why cycle world got 108 bhp on a dynojet dyno for a standard bike vs 85 - 100 ish quoted here?

thanks

Perhaps press bikes have been tweaked a bit and specially prepared?

I believe that Geoff at Hilltop correctly guessed at a press-bike which someone took for remapping. It's mentioned on this forum somewhere.

It would appear that those bikes were less constrained.

It's an open 'secret' that press bikes are tweaked, including WBMs. Always have been always will be.

This would be my bike - a March 2008 MU 1200GSA fully loaded. After it was remapped by Geoff he commented at the time that it was the most powerful GS he had seen at the time in terms of power output (109 bhp at rear wheel) and torque (89 ftlbs at 5,200rpm). He also said the linear profiles suggested to him that the bike had different cam profiles from standard. I mentioned that the bike hadn't been originally purchased via the dealer network - it came direct from BMW UK in Bracknell - this is all in the log book. That of course led to speculation that maybe the bike had been part of a "special batch" from Germany.

looks like zee germans are more devious than th austrians - ktm 1190 was tested at about 128 bhp which is consistent I think

"The first thing we were dying to find out was if the 1190 packed as much of a punch as we suspected it did. So, first things first, before taking our standard Adventure for a ride, we strapped it down for some pulls on our Dynojet dyno. And the results didn’t disappoint. The 1,195cc, 75-degree, LC8 V-twin produced 128.8 hp at 9,360 rpm and 81.3 pound-feet of peak torque at 7,670 rpm. For comparison, last year’s 990 Adventure Baja made 89.7 hp and 56.7 pound-feet of torque, while the ADV class power leader, the more street-oriented Ducati Multistrada, makes 134 hp and 82 pound-feet."

I managed to get a grown up to help me upload a dyno chart of my bike at hilltop.
The before and after feel of the bike mirrors the look of the graph.
The extra power is there if you want it, keep the throttle pinned and it just keeps building in a way it never did before.
At the lower end it is so much easier around town on part throttle openings, it doesn't jump around anymore.
