Motorcycle diagnostics & diagnosis, wiring & testing at mono motorcycles

It’s been a week of diagnostics, diagnosis, wiring & testing this week at the mono motorcycles workshop.

On Monday we welcomed the Yamaha Super Tenere.

The Tenere joined us for a wiring adjustment to the heated grips. The customer was finding that the grips were draining the battery, so Daniel has re wired them to go off with the ignition.

The SpeedTriple joined us for a deep clean, detail & ACF50 treatment. The winter salt had got into the paint & to add to this, the motorcycle lives by the sea.
The detailing process & ACF50 treatment can help prolong & preserve paintwork, but does need to be undertaken regularly to have a long lasting effect.

We have welcomed two Suzuki GSXR 750’s to the mono motorcycles workshop this week.

The first GSXR joined us for a power drain assessment & for fitting of a neutral light switch. Our customer had concerns about his GSXR starting & it seeming to flatten it’s battery. He advised that he had changed the battery but the fault was still there.

Daniel decided he wanted to try & replicate the scenario the customer was describing & therefore over a three day period he tested & re-tested the battery & charging. These were his findings:

Carried out a parasitic drain test 0.05 -0.1amps

Reconnected & tested at 12.07v. Tested 6pm 04.05.2020 at 205amps

Tested again 9.30am 05.05.2020 – 192amps/ 11.92v

Tested again 4.40pm 05.05.2020 185amps/11.86v

Disconnected battery over night 11.86v. tested 180amps. Put battery on a ‘Repair Charge’

Charged to full. Tested at 12.7v / 282amps – 06.06.2020 Good battery.

Checked continuity at the lead for the optimate charger. Open circuit, fuse blown & bare wire. Replaced with new lead.

The second Suzuki GSXR 750 arrived at the workshop on Wednesday & was booked in with us to assess a starting issue.

Upon arrival at the workshop, the GSXR was showing a temperature of 108 degrees. As the GSXR was running so hot, the oil was checked & there was nothing in sight glass. Once the GSXR had cooled down, we added a litre of oil to top it up.

Daniel then checked the radiator, which was dry. The coolant level was topped up with 1/2 ltr of coolant.

When Daniel tried to start the GSXR, it could be heard quite clearly that it sounded like the starter motor had failed. Daniel removed the sprag clutch & found water & oil mixed together. Daniel then turned starter motor with no drive to engine. The voltage before starting was 12.7v & once started, the voltage slowly rose to 13.3v (should be 14.2v) At this point Daniel knew that the major issue was that the GSXR needed a new starter motor.

As is usual with charging issues, Daniel needed to test the ECU & the stator outputs. However, we needed the GSXR running to enable this to happen. Therefore, with Katy pushing the GSXR, we managed to bump start the GSXR.

Once inside the workshop & running on the ramp, Daniel lifted the tank & found the air box was not attached to the throttle bodies.

Once Daniel had located the plug for stator to rectifier, he began a 3 phase test of the stator via AC testing:

1 phase @ 3000rpm 60v

2 phase @ 3000rpm 0.169v (Burnt out)

3 phase @ 3000rpm 60v

As phase 2 was reading 0.169v at 3000rpm, Daniel knew the GSXR required a new stator. (Unknown if needs new regulator rectifier at this time, as stator needs to be charging to test this correctly.

As Daniel moved the GSXR around the workshop, he could feel the front wheel was notchy. Having suspended the front wheel, he spun it & the distinct grinding sound of a collapsed bearing could be heard. This one was so bad, is was deemed dangerous to ride.

Having reported our findings to our customer, he has agreed to compete the works we have discovered.

The second Suzuki GSXR 750 arrived at the workshop on Wednesday & was booked in with us to assess a starting issue.

On Wednesday we completed works on the very lovely Honda VFR1200FFD.

The VFR had been transported to us from Gatwick as a non starter, as her owner said “I didn’t want her going anywhere else” Such a wonderful compliment. Once Daniel had ascertained that the battery had failed & had adjusted the rear brake (the VFR1200FFD has a hand brake) her owner was able to collect & take her home.

The fact that even during lockdown, people have been seeking out ways for us to complete work for them either by posting us sets of carbs or moving entire motorcycles safely to us; is a testament to the trust our customers bestow upon us, which is unbelievably humbling.

On Thursday we welcomed a simply eye popping custard yellow Brand new Honda Monkey Bike in to the workshop, to help helicoil a rounded bolt in the rear shock. Such a fun & stunning little bike.

We are mindful that lockdown is still in place & despite the fact that our Prime Minister will be laying out Phase 2 of the UK’s COVID19 transition to the ‘new normal’; we still have COVID19 protocols in place to protect us & you & we will continue to do so for the foreseeable future. Please see our COVID19 section of our website for further details.

We are very excited to be hosting our very first virtual breakfast club quiz on Sunday 24th May, 9.30-10.30am live on our Facebook Business page (we hope to have professional microphones in place by then, to improve the quality of the sound) The quiz has a voluntary donation scheme attached, to raise money for SERV Blood Runners who as always are supporting our incredible NHS.
